Wibbly-wobbly physics puzzler World of Goo is free on the Epic Games Store now, and in a couple of weeks it will be followed by spooky narrative experiment Stories Untold.
World of Goo has been around for so long now and has been part of so many sales and bundles that I can't imagine anyone not owning it for multiple devices, but maybe there are still a few of you. You can get it for free between now and May 16. It's good! I mean I don't think I have the energy to play it yet again, but if you've missed it, it's a cracking physics puzzler with loads of character.
Stories Untold is a bit more exciting, though. No Code's eerie compilation is a clever, unique romp that you're absolutely better off experiencing blind. You'll get to fiddle around with archaic machines and in text adventures across four stories, always interacting with chunky bits of tech, from CRT monitors to old radios. Check out Andy's Stories Untold review for more. You'll be able to grab it in a fortnight.
No Code's also working on the intriguing Observation, where you'll play a space station AI that spends it days watching the station's inhabitants. It's due out in May on the Epic Games Store.
