Really cool game, I reached level 5, but the fact that it resets to level 1 if you die was kind of annoying. Wasn't expecting the upgrades but they were kind of cool. Also I don't understand why but sometimes on level start and between waves, it moved automatically in circles until I gave input. Also found an exploit where you can just melt the bosses by quickly moving in opposite directions on the boss. Great audio and sfx as well, very impactful. if the input was just a little more responsive, you would have something really great here. Great job on the entry. Well done
