To celebrate the release of my first android game in the market the FULL version of Droidkoban will be available for FREE for 24 hours as "Droidkoban Lite" in the store. Get it while it's free! After this 24hours offer the Lite Version will be uploaded again which only has 5 levels and no achivements.
The game is a sokobal clone using OpenGL ES to put some nicer graphics onto your device. The version you get as Droidkoban Lite in the next 24 hours includes all features of the full version. 50 levels, 3 graphic sets, achievements, twitter support.
If you want to keep the full version for free don't update it! It will revert to the Lite version which will only have a few features and less levels!
I would be really happy if you have a look at my game.
