Nice job for your first game jam!
Here's some feedback.
Okay, bringing flies to take the bone and spending them is the theme interepretation here... That's it, in my opinion this is really weak :(.
The gameplay is okay, though the platforming is a bit jank and maybe unecessary... The minigame is nothing really special.
Audio is cool, no sfx though.
Art is quite nice but some of the things don't display properly (minigame) or seem mismatched....
The game does not have a lot of polish, but it's simple enough so it's fine.
Nice work!
