18 challenging levels to master

3 highly qualified physicists to play as

Steam leaderboards and achievements

No superfluous powerups, coins or XP systems - just deadly serious scientific research

Details and a trailer are waiting for you below, in the testing chamber.

Steam contains a few of these ‘runner’ games now, though the rotation mechanic is a little bit left-then-right-then-left-again of the norm. You can sprint through those tubes as either one of two human professors, or as “the rodent-controlled robotic lab assistant”, though I’ve no idea if there’s any difference beside the player model. You can also sprint through eighteen different levels and compete for faster times on leaderboards. It sounds pretty straightforward then, which accounts for the $2.99/£1.99 price tag. If you need convincing, the free version is still available for download for Linux, Mac, and Windows PC via the Boson X site.
