In this game, you teleport somewhere new every time your character blinks. This is a game about figuring out the rules of how that works, and using that knowledge to get to the end. It’s really great!
When you figure it all out, you can speedrun the whole thing in minutes, which I really love. (Some people have been calling this sort of thing a “knowledgevania”, or, even better, a “metroidbrainia”! Amazing.)
