I love the hand drawn art style. There's quite a lot here for a one man show, great work! I was pretty confused for a lot of it, like what my objective was or what I should be doing. I did slowly pick up on it though.
Something more to distinguish the fresh graves would have helped me waste less time checking every grave at the start. Maybe some fresh flowers or something. I also noticed quite a few y sort issues with the tiles. Maybe the player's origin was off or something?
Once I had all the pristine body parts I had no idea what to do next, though I did eventually find the ending screen by wandering around. I also never figured out what to do with the custard but I got through just fine anyway!
