Hey, I really liked the styling for the intro, I don't think I've seen something like that done before! It felt a little clunky to play, but I could kind of see where you were going with it. It looked like when you fired a lot of fireballs in succession, the animation would kind of strangely replay, and also one of the alien/zombies walked through a building and I couldn't shoot it until it walked through again - I would have been pretty lost if I hadn't happened to see it walk through when it did.
Thanks for uploading!
