The black and white adventure game Minit can be beaten in under half an hour, but only 5% of players have. One of the game’s designers shared some completion statistics on Twitter today, one of which showed that an incredible 0.3% of players defeated the final boss but never finished the game.
5% beating it in under 30 minutes isn’t quite true, since the achievement is for beating it in 25 runs (of one minute each), however there’s a character you can unlock that doesn’t have a timer on them so you can play as long as you want. At that point, the only required resets are for resetting the world for events to happen/unhappen. My Minimalist run was something like an hour but with under 10 resets.
