Thank you very much for your comment ! :) If you notice it you can see that everytime a character dies the score is growing slower. Sadly I know it's too hard, at the first place there was only one crate running all around the screen and you had to avoid it one side after another and my idea was to get this crate faster and faster. However I didn't manage to do it (maybe if I had more time I dunno) so I just got more crates along time, and now it's nearly impossible to survive longer than 30 seconds... But it's my first game ever and I'm proud of myself, I think I've learned a lot from this experience ^^ Thanks again
