The art is pretty bad, but the gameplay base is great, there are few things i would like to see:
1) More characters like Hornet, Quirell, etc.
2) Cooldown on attacks because at the moment you can just spam attack and fire a constant beam of death
2.1) In addition to the previous bug i think some iframes after hit would be great
3) Variety between characters because now everevone has same attack only specials are different
3.1) About specials shade is meta because the others are melee attack in game where anyone could just mash attack button and kill you instantly
