hmmm
first off, I have to say, you get definite props for somehow making us actually want to play this despite the HORRIBLE engine...
aside from the engine beign awful, which probably isn't your fault, it was great. The level design was.... fuck you... I guess.... I found myself saying "why the fuck you you put an iron maiden there, you sick fuck?!?" on multiple occasions.
Only other critique would be that i felt like the game was largely about the character animations, it remidned me of fancy pants adventures. The death animations were awesome, but there should have been more detail in the character animations during the 10% of the time you spend alive in the game. some attention to detail, simply by adding a bunch of animations that are somewhat hidden (such as the headbanging and throwing up \m/ when you you quickly tap crouch in fancy pants) character animations would have made this game amazing.
