I managed to reach the final platform, and I think the art you made is good, keep working on the project!
You said this is your "first time using Godot/code and I only had one day" and yeah that is not enough time to learn coding, Godot, and finish the game. I used Godot 4 and had the full 72 hours and barely finished my game on time while having to sacrifice some sleep unintentionally. If you're primarily an artist and not as interest in coding I would recommend looking into GDevelop which is a free no code tool with web exports and online leaderboards.
