28.08.2016 - Super Putin Bear Rider
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.
My entry, "Super Putin Bear Rider".


Have fun!

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!

02.11.2014 - HitBlock Deluxe 1.6
And yet another bug fix:

Fixed a crash in a user level with custom script.
Additionally the short cuts to modify the game difficulty on the fly did not work quite right.
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!

01.08.2013 - News
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.
C64 Studio 2.9
Add: Build Macros ConfigName and ProjectPath
Add: Command line tool MediaManager

Breaking Change:
Fixing the lo/hi-byte operator now makes expression like # In case of doubt add paranthesis! #<( buff + $20 ) or !byte <( a + b )


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.

LD #20: The This Quest
And Ludum Dare struck again!

Can't stop myself
And yet again distracted by a challenge!

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.

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.

News 03.10.2009
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!

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.
