Really great job for a first game! The enemies weren't overly punishing or unfair feeling, which I feel would have been easy to do with this type of game. Controller support was a really nice touch, although the attack button didn't work for me, so I had to go back to keyboard and mouse? Not sure if that was something on my end or a bug!
I like the idea that some power-ups help you get past an area but have negative consequences. Would be interesting to have to choose between several to figure out if you want to focus on– combat or speed, for example.
I agree with another comment that the description overpromises a bit, but that's easy enough to change! Great work and keep it up!
