I could have sworn this game was made by FlyAnvil. Whoever made it, it's a very enjoyable game. I like how you never know what kind of weapon you're going to use. Granted, that's probably because I'm not playing the game properly, but it's still cool. I like how it's something that everyone can associate themselves with. Not everyone can associate themselves with fighting zombies or really no one can.
The omnious music made it sound pretty cool too. I like how there's this one worm thing that counts for more insects when you kill it. I was thinking the level would end when all the bugs on screen would die. There's still some left over. At least you always have a chance to kill them!
