Hey, I remember you from the Coco Code Game Jam, where we both made a snake game. Nice to see participating here too!
This game concept is very interesting and meta, funny thing is I had the same idea of making a game about game dev, but after just a day, I figured I wasn't a good enough game dev to actually make it. So congrats just for realizing that idea!
As for the game itself, I do find hard to grasp, but eventually after a bit of struggle, I managed to somewhat understand it, and find quite challenging but also fun! The visual and the great music definitely helps with that.
If you're planning to develop this game further (which I think you should) maybe you can make the guide a video or better yet interactive?
In any case, this was a great concept, executed quite well, amazing work!
