This was a fun platformer! I'll echo what others have said about the camera being off-center when you are moving left, making it harder to hit jumps in that direction. Other than that, the graphics were easily readable and the controls felt good!
Thanks for your opinion. Camera's problem is fault of the resolution of this game. This game has Aspect Ratio 1:1. If I would make a game with Aspect Ratio 4:3 or 16:9 it will be better with this camera.
