Great implementation of theme, I though. That was a really clever idea and was executed quite well. The soundtrack was good, but started to get repetitive which is absolutely to be expected from a game made in such a short amount of time. I really liked the character designs and that you managed to get different enemy types in there and the revive mechanic was great as it allowed you to keep playing and having fun. Every now and then the characters would switch without me doing anything and it was unclear as to why that was happening. Not sure if that is a bug or if some enemy effect or something. Overall, really well done!
