This game is wonderful, a really great rythm game with some good music and a cute asthetic.
The real drawback is the lag. Even on low quality, every so often it doesn't see my keystrokes until it's too late, resulting in a 99.9% run. Not too good.
Oh also, I don't know what your native language is, but PLEASE get someone on the team who has a full grasp of the English language. I'm afraid I don't know what "polen" is.
Its an alright game. It doesn't stand up to the great platformers, due to lack of life system - dying and never gaming over? That says that you didn't intend this for gamers with skill. Crisp and clear animation saves it from being dismal, as does the action. Basic gameplay rethink is necessary though.
