Great game! I think the wave progression/enemy difficulty was really good (I did beat the last boss). Also I liked the different behaviors of the enemies, especially the bashing movement of the blue-ish ones and the big green ones. I did end up skipping ahead to max out, although I was one away from attack speed max. Until then, I had been holding back on upgrading some things, like jump and speed once I could reach the higher platforms, since he started to get a little unwieldy. Really fun!
