It seems to be missing one of the files to play it. Godot outputs 2 files, the .exe and the .pck. You can put both in a zip after it's exported. Looks cute based on the thumbnail though
I gave it a try! I liked the character sprite and trying to avoid accidentally catching the red fish definitely makes it more interesting. I think it could be fun as a high score arcade experience if it didn't go on forever 😁
