Nice game! I get this feeling of imminent horror approaching me X_X
- The controls feel a bit odd, there is some sliding a low gravity - it seems like you're using rigidobodies for jumps/movement and I'll suggest to maybe trying to code your own movement logic. It can give your more precision and control over what you want.
- The game is a bit hard.. I kept missing an attack because I couldn't see it too clearly. Maybe some extra signalling for an attack could work to give the player the chance to evade.
Really beautiful art! Great work!
