I've only played this for about 20 minutes so far with my partner, but already love the style and puzzles. (Oculus Quest 2)
I didn't realise the demo was just the one area (I hadn't spotted the 'buy full game' sphere off to the right) so as soon as I noticed, I bought it. Looking forward to any future updates, still adoring the textureless graphics style, and really glad you went with that option - it adds a nice solidity without the potential for distraction by textures that happens with some games.
