Oh, it was cancer
I was wondering why everybody turned green when you hit them. For being something of such low quality, it actually did get kind of challenging the more it went on. I think the funniest part is how the stick figures scream when they die. It sounds like you used stock sounds of Sam Kinison or something. The weakest part is that there just really needed to have more work put into the graphics and quality. I love games that have waves, but this did not even seem to give you a reward for kills or anything.
