Alveole, a short, experimental puzzler coming to Switch on September 1st, has only one mechanic: running.
As the faceless outline of a person, you'll be locked in an "imaginary cage", according to the developers, and you must "understand how to use this opportunity when the whole world around consists of hints." The game was originally developed during a hackathon where the theme was "cage", and eventually became a full-fledged release.
The circle that you see in the screenshots is basically a hamster wheel, and you're stuck on it, running in place in order to solve the various puzzles in the game.
Check out some screenshots:
Alveole will cost $4.99/£4.99 when it comes to the Nintendo Switch eShop in September, as well as PS5, PS4, Xbox One, and Xbox Series X/S.
