Nice game for only having 2 days to make it! I like the character, reminds me a bit of Homer Ball from The Simpsons game, and having to collect cookies reminds me more of him ahahahaha. Some sounds would have been nice, but I started learning Godot recently too and I know some simple things take more time than they should when you don't know how to make them so I understand you focused on the playable part.
Good job!
P.S: Adding coyote time would be nice, not strictly necessary for this game but for future ones would be great
