I found the game too easy and beat it on my first try. I didn't actually need the boom box and only learned that you are suposed to take it with you after reading the bottom text. I don't think you should be able to see zombies in the dark. You could do this using sprite masks or the light weight pipline. Otherwise you can just run straight through without the boom box. The art was great though and I really liked the sound effects. The bridge moment was also very nice. Awsome job!
