Bonus level behavior is weird with single-muscle control modes.

[aarontabor]

When using the single-muscle control modes (auto-left and auto-right), the game play during bonus levels is not as we intended. Each time Momo breaks through a platform, he slowly falls diagonally towards his auto-direction (i.e., left when using auto-left, right when using auto-right).

Ideally, Momo should fall straight down until he hits the next platform.

This issue might deserve further discussion, because we are starting to have a lot of special cases in terms of controls for the bonus level. Maybe we can take a step back and solve this problem on a broader scale.
