What we tracked
We first recorded this on 14 October 2026. Listed on Steam. Picked up from Steam, then checked against the store.
What the developer says
Is this working? No, the numbers aren't showing any changes. Perhaps the CommGear is malfunctioning, or is the underlying theory itself flawed. ... I'm going to need more time to get it working properly. It's too bad I couldn't speak to you, so I'll leave these words for you instead. After all, it's still possible this is a one-way transmission. This is a collaborative experiment between you and me...

Common questions
Is it really free?
Yes. Prolegomena To a Hyperdimensional Interface That Will Be Able to Manifest From Three-Minute Interchanges Experimental Demo is free right now on Steam, with nothing to pay.
Is this the full game?
No. A demo is a portion of Prolegomena To a Hyperdimensional Interface That Will Be Able to Manifest From Three-Minute Interchanges Experimental Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.
Where do I claim it?
On the official Steam page. We link straight there — we never host game files or act as a middleman.
