Overall really good game, theres just a couple of things its missing. One, game juice (Screen shake, Particles, animations). Two, Animations, and i found myself getting stuck on the nose maybe try using a diffrent collider like a capsules then freeze the rotation. one last thing that is it needs to be more flex-able currently i got stuck at a jump because i didn't find a place to give my coins away. But other then that i like the story and you executed the theme in a very good way. With a couple of tweaks this could be a Amazing gam.
Pls don't take this as me being rude, this is just constrictive criticism.
