Since art is one of the things that people notice first. Bravo on that. Short intro to story. Well done on that. Juicy attacks. Superb Job on that.
BUT the motion blur takes away from all of these. I understand that your intention was maybe to simulate a 'toxic environment' / 'dizzy' feeling perhaps? But that is not interfering a lot with the gameplay so do rethink on that.
Apart from that, everything is extremely well polished & thought of for a jam game. 😄
