More than 1 day is over, and this is where I stand:

Not much to do there yet, but finally got polygon collision detection for the first time in one of my games. Took me quite some time. Started implementing it yesterday evening and couldn’t get it to work right, so I went to bed. In the morning I saw my bug and was able to get it running. Check it out yourself.

Also, this is my first game where I used checkered paper and a pencil. The theme was Minimalism, right? Hello?

Anyways, got to have breakfast now. This will be a long day if I want add all the stuff to the game I am thinking about.
