Rotation Walkthrough Cool Math Games
This is a platformer in which you can rotate the playing field. The field rotates in one direction and you need to choose the moment for jumping, running and rotating the playing field. The game has zones in which you cannot rotate the playing field, thorns, black bodies, bullets and so on. The game is quite simple and I think in 10-15 minutes it can be finished the first time. There is also a speedrun in the game.
