For being made in a week, I thought it was pretty good. A very good tribute to a very good game. Only downside is it left me wanting more. The world building and opportunity for a sequel/new game is very high. Heck, I would just be happy if they added more levels. Not nearly as challenging as the original game, but I suck, so thats a good thing. Also a hard 3d Platformer isn't as fun as a hard 2d Platformer in my opinion. Please add more, Im begging you. What do I have to give? Blood? First born child? I'll do it!
