Tested the game and it's working properly on a single enemy, with all the main ideas implemented. The enemy takes damage and dies, after a few seconds of being dead resurrects and begins haunting you by walking slowly towards your position(think zombies!). The twist is that if you shoot at them the bullets return right back to you. Also, the camera focuses (slightly freezes) at the enemy when they come in contact with you and I expect to put certain haunting audio dialogues (like "Could you pass on this message to my son?") I will continue Day 5 with GUI and making a second enemy type -- a Grenadier who shoots bouncing grenades I hadn't planned on implementing originally.
