In terms of screen-scrolling, there are some exceptions. If the Challenge mode is enabled on a level that requires the player to go backwards, the screen will not scroll down instead.

The Challenge mode can cause several glitches in the game. For example, if the player jumps in the small space between a wall and the left edge, the player will float. If the player repeatedly jumps and wall jumps from that location, the player can go over certain parts of each level. If there is a ceiling above the player while doing so, the player will get stuck in the ceiling and be pushed away from it.
