I abandoned my effort to port the game from Godot 2.x to Godot 4.x. The process was hard and was too big for me given my time and skill. Recently, I decided to ask Claude Code to create a PWA Web App from scratch using the Godot 2.x source as the spec. After about 1 hour and $24.63, this is the result. I have only started testing the game, but so far so good. Check it out! https://pathsliderweb.amayfield26.workers.dev/
