Great game. Love the art style. It's very fast paced, which makes the beginning difficult, but once you level up, the abilities really start compounding and you become a beast! I would maybe suggest an auto fire in the style of a bullet heaven, but if that's not what you were going for I think it's great as is. If you do leave it on manual button mash, then I would suggest allowing power-up selection with WASD and select with SPACE because I'm navigating with my left(WASD) and mashing with my right(SPACE). When I have to select a power up I'm likely to get hit coming out of the menu before my right hand returns to the SPACE bar because of how fast the games is. Amazing job!
