Nice little game :) The difficulty progression was good, with the game getting a bit more difficult after the player just gets used to the controls. However, it seems as though it was pretty easy to just kite the enemies around without taking damage, which defeats the purpose of reserving clicks. So once you run out of clicks with no more items on screen, you just either move around for a while or give in and die. Besides that, it was a pretty nice and well presented game.
