Aww I really want to play this because I developed something similar, and ALSO in Godot, and would love to compare! Except I am running into a Stack Overflow error when trying to start the game. I'm on Brave 1.83.109, Windows 10. Specifically:
"Stack overflow! Stack cookie has been overwritten at 0x00541530, expected hex dwords 0x89BACDFE and 0x2135467, but received 0x3cb88c4b 0x3cb5737f)"
If I had to venture a guess, something is causing a recursion error, like trying to load the game inside its own script.
Here's a thread on the Godot forums which may point you in the right direction:
