Have fun and use savestates responsibly (or don't at all). Starts off Kaizo 1 difficulty, ends kaizo 3 difficulty. Uses many creative designs, traps, boss fights, challenges, and puzzles. Slight palette changes; otherwise vanilla.
The title screen. Features a wall-jump.
Practice level in Yoshi's house.
Shell jump puzzle?
A useful Blargg in a vertical cave level.
Action packed level with tons of gimmicks.
A clever puzzle level.
Clappers + Baseballs + Falling Platforms + Kaizo Blocks = Not that hard!
You can't see any of the ground in this level unless you turn on the lights?
The invisible elevator level.
My favorite puzzle level. Good luck!
And, finally, this hack comes with a pretty, non-linear overworld with great events.
