Loved the game. The art is super cute and I enjoyed the contrast between the dark themes and light hearted artstyle.
Main thing to improve is the controls: because attacking and moving both use the same key, I Found myself clicking on the ground near enemies and running towards them accidentally when trying to attack them.
Also the enemies AI sometimes gets distracted when attacking you and start attacking Graves instead, which breaks the connection to them and feels weird.
I loved how at the start you introduce the games mechanics in a safe environment, it taught me the mechanics and made it easy to jump in to the full game.
Good game, well done.
