I tried to keep upgrading attack speed, but it maxed out... after that I was surviving by dodging... until. I couldn't walk back any more. Fun game, at first I didn't know how to get the shotgun, but then I saw the Icon change on the top right when I ran out of bullets. Fun game. Could be taken further with more polish and mechanics. Art style is calming, but gameplay is unnerving, especially if you press Space without the shotgun xD
