The character art is very nice, but I wish the environment matched it. Feels like some features aren’t really used or fully fleshed out, and the "invincible" theme could be integrated a bit more. Audio I think could be good but it needs to be integrated better, it's repetitive and there is too much overlap. Could look into the attack collisions, it seems a bit incosistent, maybe make the base attack a 180d sweep in front so you're hitting above and below you as well.
Overall, the game is fun, good job!
