I really like the pixel art. Props to the artist. I had to turn off full screen in the project settings though or else there was no way to close the game if you get stuck (Like missing the first crocodile jump). The music is cool but I like a little more upbeat. You could also use get.tree.change_scene() to jump to new areas. Over all though I liked it and I would definitely play a more fleshed out game. Good work.
