The Kaizo Dimension
This hack is 9 levels long, has an RPG Overworld, custom blocks/sprites/music/LevelASM/HDMA/etc.
A mix of kaizo and puzzle levels of varying difficulty (medium-hard to slowdown-needing-hard to
that's-just-plain-unfair-hard), with a custom final boss I wrote from scratch, and one level that
probably has one of the most complicated kaizo traps ever .
Have fun playing/TASing/etc!
