Hey, I started running this mod today as I discovered it and I noticed a glitch in the game that might 'break' the rules in a way:
It allows you to "teleport" to CORRUPT level from the tutorial level, without ever leaving the game to the main menu, which makes the run about a min and a half long. Even though it might sound obvious, I was thinking it's worth mentioning that you need to complete all levels in the rules...
I've been able to reproduce it several times so it's not a one time glitch
