This was a fun game! It made me laugh and the art was fun. One suggestion would be to give a visual feed back / camera shake / or noise when taking damage. The game play is intense enough where I didn't even notice my health bar until it was down to 50%. Then I purposely touched an enemy and couldn't tell I was damaged other than the health bar. My other suggestion would be to make sure the enemies aren't spawning so close. They would just appear out of nowhere. I think the room is large enough where the enemies could always spawn off camera. Or if you put in a spawn effect like they were being summoned or something that would be better than just appearing. That said, well done! Brought me back to Robotron.
