Seconded, this game could really use controller support

Something else you could do is make them non-permanent forms as a sort of debuff and make it so if the player leaves the area they go away. That way instead of having to make animations for a cursed form for every enemy in the game, you'd only need it for the enemies specifically in that area. For extra clarity I'll elaborate on an example just in case: if you had a slime tf that wasn't game over you'd need sprites for if a slime grabbed the player while they're in slime form, but the second the player leaves the room they lose the slime form and no other creature in the game needs to be able to interact with the players slime form, thus saving much time and effort for a very similar effect.
