Given how you only started learning Godot a few weeks ago and this being your (our, in fact!) first game jam, I thought this was well done! I really like the main menu, too!
I think it would have been cool if you could pick up the key, and then somehow be able to get up onto the cage to unlock it to release the trapped cat, rather than magically opening the cage after clicking F :D
Good luck with the rest of your game dev journey!
