Game change:
A big red button on the setting screen.
Recently, a few speedrunners found this game. (Which is a big surprise to me)
They demand this button to reset progress.
Check https://www.speedrun.com/yapp for their amazing runs.

By the way, my latest game, Understand has been published on steam.
It's a line drawing puzzle inspired by The Witness, but you won't think it's a Witness clone or Witness lite.
