The ragdoll physics made it a lot of fun to just walk around, and then the shooting on top was even better! The floaty jumps were also great and fitted the feel extremely well. Great job!
My one little criticism is that it was really hard to hit the AI for me. They would always hit me first with their flawless aiming. Once I managed to kill the enemy, but it was really difficult, haha. Maybe if there were more enemies the attention of the AI would be split?
Really well done in three hours! This was a lot of fun to play :D (Even if I was really bad at it :P)
