Cool! The bullet shooter part of this works pretty well, and I do like the idea of swapping bodies to get different guns and get new health. Though I feel like the whole alien possession thing is maybe impossible to do if you're already being shot at? You can't get behind them as they turn at the same speed you move, and you die in one hit. So basically it's just a shooter, where occasionally when someone is turned around, you can change into them. Overall though it was pretty fun! Nice work :)
