The music is amazing! Also love how the characters steps go almost perfectly in sync with the beat. There was some weird stuttering/lag in the basement & second floor that caused framerate and audio to become choppy, bearable but unfortunate because that track was sick! Loved the ghost animation and the idea for the spider enemies with the shadow that appears first, though they could use an extra half second before dropping as it seemed like you were out of luck if their shadow appeared directly over you (maybe intended?)
Edit: Adding that your cover art is ridiculously good. Keep it up!
