Good game. Our hits, (and sometimes the movement) feels a little off, though.
I wish there was a melee/block function as well; but that is hot off the heels of an "almost" complete (upgrades) run.
I liked the way the armor worked - You will need it after a few waves, and contrary to the other upgrades, you need to re-buy each tier as you lose them, with their original pricing. Will you get yourself protected, or trust your skill (and risk everything), and max your other upgrades?
GG!
