This is a level that took me about a week to put together. It's my first big level, and I'm really proud of how it turned out. I was going for a Dark Rapture-ish difficulty, and I think I succeeded in that aspect. Please give me some feedback. I would really appreciate it!

Again, please comment. I really want to know what you all think of my level!
