I say its worth giving it a try. I'm new to all of this myself. I've done a few Godot tutorials so the idea of making something from scratch in such a short amount of time is scary but I'm really curious to see if I can. I encourage the same for everyone. At the very least you'll learn something through the process, at most you'll have a game you can say you made in a week. But totally, as KoolMelon said above, there's options. Give it a try. You might surprise yourself with what you manage to come up with. Hope you join in and learn a few things for the future.
