I love the character designs (especially death's!)
The background could use more refinement, but it is still quite serviceable
The gameplay is fun at the start but can get quite repetitive, so can the dialogue for death. Its good but maybe couldve used to add lore and tell us more about the cat and death's relationship. How they found each other and became friends.
The game is still quite fun and charming!
And also the game seems very polished and bugless. You did really great!
