I don't agree that this was a good game. It wasn't necessarily hard; it wasn't too new or interesting in fact. After a few speed boosts, I could just pump the damage repeatedly. Zombies kept spawning in such a way as to shove other sprites forward; that's not hording, that's bad programming, but not something that couldn't be overcome. I was amazed though that at one point, the game suddenly had a jump in framerate and speed no reason, and then I was quickly overwhelmed as I no longer had time to even select my next skill point.

It's not terrible, it's an improvement, but it still have a long way to go.

I'm happy to see a game that actually works. You can at least try to get a score, but I have to say its not too original. Maybe you could add increasingly difficult enemy variations or waves, or maybe you could have to get from point A to point B, or do something without dying? At least something to measure the score, because you never run out of ammo pretty much as long as you don't suck at clicking. At least its a little functional and has some possibilities.
