Good work! I like the feeling and the flow of it. Having the goblins go faster and faster as you build up combo keeps the pace going very well. I also like the risk/reward aspect of keeping a high combo, and the fact that losing the combo on accident and not between waves almost always means death because of the cooldown. I like the juice that's there, even if it could be even juicier, and I like the post prod effects as well. Good job. It's nice to have the big combo meter in the center of the screen, that's a very smart decision and really drives the theme home!
