The word 'meatworld' reminded me, did you know you can play Yume Nikki and many of the popular derived works online?
https://ynoproject.net/I suggested .flow as halloween game for Gigi and as I was catching up on how to setup I was made aware of this. That wasn't in the cards and she hasn't really brought them up as backlog or anything so I thought perhaps Champoos would like to take a stroll together in some of the games some time.
In all honesty, I don't think there's really anything to be gained from a multiplayer aspect to these types of games. To me they're a very isolating and atmospheric kind of experience that's best enjoyed in a quiet dark room. But it's possible. So that's a bit indresding I suppose.
