Not really a manual, but more of a 4th wall derailment into a fever dream of sorts? With a lot of reading while navigating a mystery? And some match 3 tower defence action in between?

Titanium court.

For more of a game with an actual manual focus, try - King of the Bridge. It’s a game about chess. Mostly.

With the whole spiel of “you can press a button and the game will play itself for you” I don’t even doubt that’s entirely a possibility.
