Back in 2015, Tom Sykes tried to explain Manifold Garden (opens in new tab) (then a few years into development) as "an exploration puzzler set in a 3D world that wraps around on itself", noting that it was inspired by M. C. Escher's Relativity. In fact, Manifold Garden was originally called Relativity. Sykes concluded by noting that it "should be done sometime next year".
One year later he was writing about the "physics-defying puzzle game" again (opens in new tab), pointing out that now it had a Steam page (opens in new tab) with a release date of 2017. That turned out to be untrue as well, and it's only now been released in 2019 (and on the Epic Store, with the Steam version to come in 2020). But it is finally real, and playable—although not in VR. Apparently they tried that during development and the results were as nauseating as you'd expect.
Here's the store page (opens in new tab).
