That it's a 3D game probably doesn't play nice with lower-end machines. I'll look into performance optimizations that are doable within a game jam.
I think I'll make a walkthrough video for those who get stuck. I originally wanted to add a hint system but unfortunately didn't have enough time for it.
I definitely agree with making it a webbrowser game. I only learned last second that .NET Godot doesn't make that easy.
Thanks for the feedback!
