Overworld is just the same vanilla overworld with layer 2 replaced with water and rocks, even the events are the same.

There are multiple cases where things like normal platforms kill you for no reason. (also yellow switch...)
A lot of blind drops and offscreen munchers you can run into because of poor camera management.
Kaizo-lite is meant for savestateless playthrough,the level difficulty is fine.. but this hack doesn't offer infinite lives or a retry system to help smooth the gameplay. I would highly recommend adding those if you want people to play it.
There is a pretty much straight edit of YI3 that basically makes you do the speedrun strats to beat the level. We don't accept blatant edits of smw levels.
