31.12.2019 - Project J - A C64 Game in several steps
Back in 2011 I started a tutorial series on how to create a C64 game in several steps. This was originally posted on Retro Remakes, GameDev.Net and Forum64. Since then several updates partially broke the posted series and so I've decided to host it on my own homepage.

This series ran for 100 steps until 2013 and created a full game, which later became Guns'n'Ghosts.

08.12.2019 - Tuck's Adventures on Meta
Tuck's Adventures on Meta is a remake of a DOS game I made almost 30 years ago.

It is kind of a Metroidvania, you find items which provide access to new areas, or new abilities. There are no enemies, but lots of holes to fall into :)

Tuck is on his way to Vokuhilon to the big snail farm auction. But unfortunately the engine fails and he has to emergency land on Meta. Stranded he now has to find a space ship repair kit (a very rare item!). Help Tuck find his way about and fix up his space ship in time!

20.11.2018 - Get 'em Good
Get 'em Good is a remake of a C64 game called Get 'em DX. It's a mixture of Pacman, a shooter and strategic extra usage.
Clear every screen of all dots. Be sure to fight back enemies, as they drop nice extras. Pickup 9 of a kind to activate a particular powerup. Once all dots are collected grab the key and unlock the exit!
Careful though, the enemies will get faster and tougher as the stages advance. So you have to be on your toes and be sure to grab enough powerups to keep up with them.

Randomized stages allow for high replayability as no two games are alike! Play alone or team up. Both players play with one score and one pool of lives. The one who activates an powerup is the only one to receive it though.

Iron Willy is a commercial advertisign game from 1997. It was written for the DVS - Deutscher Verband für Schweißen und verwandte Verfahren e.V. (http://www.die-verbindungs-spezialisten.de via the DVS Media GmbH.

This DOS game is one of my favourite projects and was created with several great gals and guys and lots of love. As a bonus the speech is fully functional! Due to the market back then it's only available in german though.

This packet is available for download with kind permission of the DVS Media GmbH.

The download contains the DOS emulator DOS-Box, to start the game simply double click the batch file "Iron Willy.bat".

The game itself is an adventure in 3 acts, an pure adventure part, a puzzle part with lots of welding and a short action part near the end.

12.03.2018 - Fan made manual for Joe Gunn
Now to something completely different:

A real fan sat down and created his own manual for Joe Gunn. The manual comes with hints towards the first puzzle, is provided as PDF and really shows it was made with passion.
Therefor I'm putting the file up for download (with kind permission by the author, Andy Haywood) from here.

Maybe the chance to undust Joe Gunn once more? ;)

Ok Comrades,

It seems Mother Russia is falling behind in the arcade stakes. So this must be rectified immediately. So I have had a note from a Mr V. Putin saying he needs your input.

Now being Russia they dont want flashy graphics and that ... See Tetris none of that high resolution stuff.

Make Russia great again with such games as Tsar Wars, Hunt for Pink Oktober and such other great games...

Thus the comrades from Retro Remakes let us know, and I followed their call.

20.01.2015 - HitBlock Deluxe 1.7
I'm currently playing every single set and see if it's solvable. You may notice that some sets had updates in November, some in January. I'm about half way through, so expect a few more updates sets.

And unfortunately a few new bug fixes:

Major one: I re-added a few known behaviour bugs, which some user level sets relied upon. Now all sets should be solvable again.
Once you win a set you should no be able to return to the main menu.
No more crashes in levels with many objects.
Speedup for levels with many objects
Speedup for the level selection screen, huge levels caused quite a slowdown for the preview.

Have fun!

There's a new extra easy difficulty setting for those extra mean stages.
With the proper short cut keys the game difficulty can be changed while playing, makes beating those nasty stages easier.

Some user levels were unsolvable, because they either used accidental features which I fixed; or they really were broken. These features are restored (like moving boxes over one way blocks), other stages have been adjusted.

Have fun!

I hope nobody got scared by the Donate button on the menu bar.

Nobody should feel forced to anything. Still, there are some costs for hosting the site and also creating new games. If you want to support new development, I'd be really happy and thankful.

And don't worry, everything is and will stay free!

In other news HitBlock is perfectly stable. The last touches are set to new stages, a few new features and most of all, compatibility to older stages. All existing stages from the online level database will work fine!

Nothing spectacular this round, but it's an update!

HitBlock is going strong GUI wise, and a lot of testing is required now. There are still quite a few bugs hidden away.

In a short time a new puzzle game should be available. I had planned it for this update but I just wasn't satisfied with the overall look.
30.06.2013 - News
As promised here's the first of the more regular updates.

Currently I'm working on HitBlock Deluxe for PC and Hyperion for C64.

Since I'm also working over the uploaded level database I'd be happy to hear your thoughts. A new feature will be a download count. Maybe also level voting but only if I can keep misuse down.

Hyperion will be a metroid like game with scrolling, lots of aliens and a dark background story. To see a few mockups head over to Lemon64.

Server moved
The provider change is done, the site has moved.

Now the recurring outages and being-hacked should be a thing of the past.

Plus: There will be more and more regular updates. Not every single one will have a download though :)
Get ´em DX
HitBlock is making good progress however it won't be done by end of this year.

On the other hand another C64 project is done, Get ´em DX. It's a polished version of the original game from 2011. This time with spruced up graphics and real music and sound effects.

And Ludum Dare struck again!

This time #20 with the theme "It's dangerous to go alone, take this!"

Not really innovative a little Zelda clone was created. The game is rather short, as consolidation there's an editor and even some enemies.

Find the game here.
The experiment experiment #3
To get things going again:

An unfinished 3d pacman game. Get the game here.
Merry Christmas
Christmas is nearly there, the super markets are preparing for Easter. Christmas is in the air.

Here's a little present. Not a real game, just a small fun toy. Decorate the tree! Listen to the music! And torch the decoration.

Find the toy here.
Laser Light
That extra brain food!

A little bit older, fixed up and made ready. It's a funny little puzzle game with editor. To download go this way.
Can't stop myself
And yet again distracted by a challenge!

This time it's a complete game, rather short though.

Imagine a 3d world, folded into a plane. And now, fold at a different spot. This makes it possible to access all kinds of short cuts. Difficult to describe, just give it a try, right here.
The experiment experiment #2
A long long time ago I tried to start the experiment experiment. It worked for one entry :)

To get things going again here's the download to an older experiment, Gyroscope Plus.

To get the download and more info go here.
C64, Penultimate Fantasy
And finally a new game. For the C64.

This was my entry for the Forum64 Basic competition. It's a little Final Fantasy clone and might even be fun to play!

Get the game here.
GDC7 13.04.2010
I couldn't resist again: GDC 3h VII.
Write a game to a specific theme in 3 hours. This time a puzzle game with the theme "spring". Result is a nice little game that even is not completely easy!

In other news HitBlock Deluxe is progressing quite well.

Find the game here.
Love Shift
A little late for valentine's day, a little game inspired by Night Shift.

Earn money in the chocolate heart factory. Maintain the big machine, keep it going and produce the required number of packaged chocolate hearts. Jump back and forth and repair the broken parts which mess up the production.

Find the game here.

And finally a real update!

I couldn't resist participating in yet another programming competition. The result is a fine little game over here.
HitBlock Final for Windows 7
Sorry guys, still not the finished version of Deluxe.

While toying with Windows 7 I noticed that the setup doesn't work right. I've worked it over and it should do its job now.

Find the new Setup here.

HitBlock Final fixed
Alas, this is not yet the new bigger better version. Since a magazine asked I've upgraded the old code base for HitBlock Final.

This version doesn't ship with all sets predownloaded, it works fine with Vista (and probably Windows 7) and also received a few bugfixes.

Due to the changes this version can not be installed as update of a previous HitBlock installation.

More about it here.

It's been quite some time since the last update!

After moving house I plan to speed up development again. Let's start with a sad little excuse for a game, once more for Ludum Dare!

Find more about it here.

And now to something completely different:

Since my interest in C# and also SilverLight I participated in yet another programming competition. The following game resulted.

Requires SilverLight 2, a browser plugin based on .NET, available for common browsers and OSes.

So hurry up into the SilverLight department!

A little update for HitBlock Deluxe.

The cooperative 2 player mode is working, the whole GUI stuff is missing ;)

And part 2 of the experiment experiment:

XOrbit. Since its WIP it's pretty rough around the edges. Try the "Nasty Puzzle" mode for a little hectic.

More about it here.

Hi there,

While cleaning up behind the old stuff box in the cellar i found a few gems under heaps of dust. For one, there's my first version of HitBlock for DOS, as well as a few other old games, now conveniently sorted in Other Programs.

In other news the work on HitBlock Deluxe is commencing nicely. I'm getting in the working mood again.

Have fun!
Joe Gunn published!
Finally Joe Gunn is out for sale!

For lovers of the good old breadbin: Joe Gunn is available on tape. The game is the same, there is a little extra for buyers included though.

The shop is here.

The game is still available as emulator file for free over here.
