Here are the problems:
-Get hurt by null space.
-Too many regenerating badguys.
-Too hard, ON EASY.
-Spaz can't get out of the place with TNT.
-Swearing. (I will cut any level with swearing's rating into 3/4 of the origianal rating.)
-Too many devels.

Good Stuff:
-Tyrian 2000 Boss!!!
-Nice MCE (and SCE?) use.
-Excellent Music
-Good Diffulculty if you turn it down a bit.

There it is! Just work on those and it will be great!
