I really like the chaos created by switching world constantly! It would be nice to have some checkpoints tho because it is a bit tedious to restart from the beginning after failing a jump and having to redo the chaos part as well as the platforming part.
Maybe if you added some mechanic where the number of enemies you kill in chaos would give you more time in normal, and when you die in normal you're sent to chaos could make it a bit more balanced while rewarding good play in both worlds, just my 2 cents ^^
Great work!
