Chronotron is so impressively playable that it’ll probably kill your productivity for the day stone dead. We just thought we’d warn you.

Chronotron is a time-travel platform-type puzzle game where the aim is to collect an object and return to your Tardis. But the only way you can do this is by sending a version of yourself into the past to help you complete the puzzle. Chronotron starts off easily enough – present you stands on a button so future you can stand on the platform that the button activates – but by the end you’re firing off so many different versions of yourself teetering on the brink of a game-ending paradox that you’ll really need to have your wits about you. Incredible.
