Minor update: end-game numerical data now displays with nicer font!!!11111
On the original Zombie Attack, reviewers bitched about bad graphics, no sound, being too simple and being too easy (but mainly bad graphics).
Zombie Attack R[evised] is essentially the same game, but with several noticeable improvements and new features. This makes it much more fun to play. Unfortunately, the game still doesn't have sound yet, since I can't get it working, but I'll find a way, and I just wanted to submit it first. So, yeah.
Known issues: Sometimes when you die, the zombies aren't cleared off the screen properly. The cause is unknown, but they quickly move off in any case. Also, the game can seriously lag on higher difficulties where there are tons of zombies clogging the CPU with their AI, which I can't optimize any further. D:
