I took on this game since I wanted to make Water Sort (without ads and probably soon open-source) that I can recommend to people around me. :D Game Jam simply pushed me to do it.
Since it is my first project in Godot, I needed to learn pretty much everything, set up whole tooling, learn how to package web build, and all that jazz (including itch.io dev account section). It took probably 8 evenings (2-6 hour per evening).
