Hi!
After a bit of brief testing, I am able to reproduce the crash, and will look into what the underlying issue could be soon. (Unfortunately not the first person to report a crash at the beginning of the game...)
Thanks for the good feedback, playing, and support!
I've been testing systems and mechanics in Godot for a few months now when I get time after work, and this process of starting small and developing progressively bigger with the same base mechanics is so cool to me. I'd love to hear more about the process behind this in dev logs or something like that!
