super duper fun! probably one of my favorite undertale inspired games i've played, has a lot of cool mechanics and content for a small game!
only critique is that i don't really feel sympathy for the duck. he's annoying (intentionally i presume) and kind of a grifter so i don't like signing the contract with him and don't feel bad for killing him.
everything else about it is really well done though. playing it with a drawing tablet is actually the only correct way to do it

this is amazing!
