This ones pretty cool, the models are disgusting(in a good way) and the soundtrack is pretty kickass, although I did find the 2d mode way more forgiving/easier than the 3d one, but other than that pretty neat.
I also thought about making a doom-esc game at the start, but after finding out the limitation promptly changed my mind, so i'm glad someone else thought of a way to make it work.
very nice!
