Hello. Remember the super dark world cotton alley mix I made two years back? Well, here's a dark world of that chapter.

Yes, I am insane. I really wanted to push the limit this time around and make the absolute hardest thing possible. Halfway through my recording process I kind of realized I've made a mistake.

Not sure if a lot of people care about this game anymore, but this was something I just wanted to do. Most of the levels differ quite a bit from the original, and once again the last two are made almost entirely from scratch.

If you can beat these levels easily, I'm fairly certain you can do anything in this game. Good luck.

Songs used, in order:
