Congrats on finishing and uploading your first gamejam submission! This is my first gamejam aswell.
I really liked your idea about not trusting the game itself. The platforming is super barebones, but I think it kinda fits for this type of game. Some nice sound effects would have helped it alot tough! Using Nintendo's music is a no-go for me personally. Your creativity makes up for that. :-) I hope you don't feel offended. I wanted to give some genuine feedback.
