Then Pony Island is for you.
It's a really weird game where you play games inside of a game. It gets very meta and interesting. Kind of in the vein of The Beginners Guide or Undertale, but with more interesting gameplay.
I don't want to tell you too much more about the game because figuring it out and seeing what happens is most of the fun. It's normally $5 on Steam but tends to go on sale a lot. Seriously, pick it up if it sounds even vaguely interesting to you.
