Well I've never made such a bad game either, but at the same time I've never made such a good game, too. So that's for the riddle 👀
I learned a lot though, it was quite different from just following tutorials. I didn't really reach the game state I was aiming for, but at least it's playable. Wasted so much time on shaders, only to just give up on them in the end. That thing is hard.
