I would say in it's current state it is definitely better with a controller

Aha! Thanks for pointing that out. I think I should have at least put a cooldown timer on the attack so that it can't be spammed but in testing I never ended up playing it this way. What I might do when I tidy it up is change the format of how enemies appear, so instead of scrolling onto the screen they will just materialise in front of the player.

Thanks for the feedback! Out of curiosity which input method did you use? I agree it is difficult but I found it much more enjoyable to play with a controller (if I say so myself)
