Hey, sorry if this wasnt clear, but the enemies only take one shot to kill. They have an ice cream on the back of their heads you need to shoot. One thing you can do thats sure to kill them is: put a ricochet trap on the wall, get an enemy to run in front of it, then shoot at the ricochet trap. I know this wasn't abundantly clear, as we ran out of time before we could really tighten up the in-game instructions. Sorry about that. I added an instructions section to the main page (and in a comment down below) if you'd like to learn more about it. If you decide to give the game another try with this in mind, please let me know if that makes the game more enjoyable :)
