Great game, few problems.
I get this game is supposed to be difficult and all, but there are some things that unintentionally add to that difficulty.
1. Some levels are WAY too cluttered and you pretty much have to lose like 3 times just so you can see whats going on in them, get a simpler color palette.
2. The level where you have to escape the giant spike wall is just retarded. There is NO distinction between foreground and background making it frustrating and annoying when you see something coming up and don't know if its a wall that will kill you or just some bit of background.
3. Make the ghost chick wider, so it's not so frustrating when your stupid redheaded asshole misses her by 2 fucking millimeters.
Theres a difference between having a challenging game and a frustrating game. fixing these issue will still keep the challenge in the game while removing the annoying little bits that make you feel like you've been cheated out of completing a level or that it's unfair and unbalanced.
pretty cool original concept though, I liked it.
