Your rabbits are cute but the controls need some work. I routinely got soft-locked, having to reset first in level 10, then level 12, then level 7, then decided I really cannot bear to reset again. The most effective means of traversal was to hold S and slide to the right or left, and to jump midair or when touching a wall, because wall-jumps are lenient and jumps are allowed at any point after walking off a ledge. Walking normally is a bad idea, because you get stuck hitting your head while bouncing in the one-tile-tall hallways at the end of some levels.
