It's not bad but the challenge/balance really is off: I was maxed out everything around wave 10 and it's just never a challenge. Maybe it gets a challenge by wave 30 or so due to sheer number of enemies, but what's the point then?

That, saving and some nice splatter sounds would be add to the entertainment ;)

I just sunk an hour into this. I'm feeling better already.

omg yes thats awesome, please add save-game functionality i wanna play more later but i have to go touch grass
