Instructions are in the game, please read them, they contain very helpful tips. And I would aprreciate it a lot if you checked the credits as well.
Lots of thanks go to Rosalie Prins and Benjamin (Inglor) Gruenbaum.
The graphics can be a bit off, I'm a better programmer than artist, sorry. Also the game is pretty much rushed because of a deadline.
