I personally really like this game. But I am very annoyed by the level where the collision is not working, and you have to look under the platform on how to walk. The camera is always adjusting, which makes you walk in a direction I didn't intend to. Also, it is very difficult to always have to count which field is which.
So my suggestion would write the numbers directly on the platform's themselves and prevent the camera from readjusting when you move.
