Some news:

The game will be released as freeware. The first release will be in playable state, but I might do some improvements when I have some time and motivation left later

I still need to do some work on the homepage - but once I'm finished you can download the game for free. If you like the game you'll be able to donate some money to help me keep the website running.

For now, you can check out the contest demo to see whether you like the game.
