Update to review: to stop game from freezing try turning off the in-game music. It helped stop the freezing for me.
The good:
Lets get this out of the way, yes this is a fun game. This is basically doom with different levels and different enemies. Im a big fan of doom and usually am pretty critical when it comes to anyone trying to copy it. Since this game is desperately trying to be doom it does a decent job.
The bad:
The game will crash often. Save often or youll have to start over from your last save.
Overall:
Worth it even with the crashes for the low price. If price goes up past a buck dont buy until bugs are fixed.
