Neat little game. I think it gets a bit hectic too quick, a lot of times my initial enemy wave would be the chompy bot and a missile which depending on when it shot made it feel really unfair. I feel like some of those might need to be spaced out a bit better. Also I feel like instead of just being random, health packs should probably spawn after a set amount of time after being hit. I often got health packs on full health and not often when I actually needed them. It's a fun little collecting game, I could see it being extremely fun if expanded on a bit.
