this was a lot of fun to play! visually I think it looks really good and fits the theme well. I think as a keyboard player, "x" and "m" felt kinda weird to use as the shoot button, so maybe "e" and "o" instead? it's probably better to use a controller for this anyways, but just a suggestion. Overall, good job!
I'd appreciate it if you could play/rate my game as well! :)
