Ahm, what? :D
I got a score of 16 and don't know what happened. :)
hey basically you have to hit the small shapes when you're small and hit the big shapes when you're big (press left mousebutton) to get a point.
Also every time you get a point, they change shapes so you have to get away fast or change your own shape.
If you hit a big one while being small or a small one while being big, you lose a point. In the latter case the shape will also disappear.
You lose if you lost 5 points (hit 5 wrong shapes). But I'm sure this isn't the best possible design for a losing condition. I think some of the most fun I had while testing was rushing into a huge wave of shapes which right now is not really possible without losing.
I wanted the game to be really weird and I like it that you have to figure the rules out yourself but they're probably more unclear than necessary. I think I'll work a little bit more on it to provide better audiovisual feedback.
