To do:
Document major changes between versions (eg. the uncolored arrow in Level 4, FPM's hurt and duck animations, doors not being erased in levels between versions 1.3 and 1.4, the version promoting the console version and having EA2D's logo in the intro, the Angry Rabbit boss fight glitch in v1.9 etc.. There's a lot of changes between these versions.
World 2 has multiple different versions, with plenty of differences between them, including some glitches sprinkled in there too.
