Considering you're the other Undertale fan of these forums, you might wanna check out "Jimmy and the Pulsating Mass." Its a 30ish hour RPG that takes place in the dreams of an 8 year old. It has graphics and tone similat to Mother 3, and I think its characterization is right up there with Undertale in quality. Its 15$ on Steam or Itch.io, but there is a free 2 hour demo. Its pretty darn good.
@Tresset: I'm not the one who figured that out! I heard about CTRL-K from somebody in the "Did you know?" thread and later tried using it to make Hexxat the main character, which I'm guessing is where you heard about it. That person deserves credit for the discovery, though I don't remember who it was.
