@Joozey: Great game! I also played "Das Überleben". What I like about the Überleben is the deep atmosphere, especially the Ice and tree level. What I like about your game is the more relaxed feeling and the rotation of the platforms.

So far so good. Though, the game is very hard, I think. The speed should be way slower at the beginning and should increase piecewise by the amount of platforms. Maybe you can also add some animations to the avatar. When you are near the tunnel wall, you can see the a pink color that doesn't match the environment.

Are you intending to take this any further?

Fun fact: I had a game in mind where a character falls down and I never thought about this perspective.. it was quiet an eye opener. I hope you don't mind if I ever come up with a game similar to yours?
