A couple of glitches I noticed at the character select screen: Whenever you select a character for an underwater level, it plays the animation of your character for a non-water level. However, if you enable the water mode cheat, it always plays an animation that employs underwater physics (e.g. Mario does a little swim hop rather than the normal standing jump to hit the question block) The underwater character select animation should play at the character select screen for all underwater levels. Some of the character selections when water mode is enabled are a bit humorous and it would seem unintentional. For example, Luigi falls short of making the high jump across the wall, and Simon falls short of collecting the meat!
