Fun enemy design, very distinctive from the background too. For whatever reason changing mouse sensitivity does not save, changes are cancelled the moment I return. Maybe the bar does nothing, I don't know. Dunno about anyone else, but I was aching for some checkpoints particularly around the time when you get the rocket launcher. Dying shortly after that and having to restart the entire game, it's not to my tastes I'll say that much
update: went back and defeated the game. enemy sounds are pretty fun as well. although most of what I ended up doing in each engagement was luring the enemies through the nearest doorway and slaying them one at a time without much variation in tactics. dunno what could be done about that, maybe changing up the enemy AI a little but that sounds hard
