Have You Played? is an endless stream of game recommendations. One a day, every day of the year, perhaps for all time.
Activate the Three Artefacts and then Leave [official site] is a name and an imperative. Fly into the giant angular sphere, navigate the twists and turns of seemingly disordered corridors and hidden passages, then get out before the white noise and buzzing bore through your head.
It's a fine free game from Stephen 'increpare' Lavelle, an unsettling explore 'em inside a giant angular structure riddled with corridors, pocked with hollows, and and concealing paths in unseen corners. A depth blur will hint at what's far away, revealing passages in the angles, but that's not too much help. With six full degrees of movement, you'll quickly be turned around, with no sense of up or down, left or right, outwards or deeper. Realising you're nearing an artifact then discovering it's one you've found before is crushing but hey, chin up: you've got a job to do.
It's an impressive place but often confusing and unsettling. I think you might enjoy a visit.
I have still never found every artifact, always giving up after two. Writing this now, I do wonder if there even are three. You wouldn't, Stephen, would you?
[Disclosure: I know Stephen Lavelle a bit. I once accidentally killed a giant basil he grew then gave to a mutual chum, for whom I was meant to be plantsitting. Sorry.]
