There is unfortunately no demo available any longer since:
1. It was not a good representation of the game, mostly speaking from a performance and quality-of-life perspective
2. Players would still have to replay/skip through the relatively long intro (1,5-2 hours) and go through the same first few hangouts again in the full game. Even though the intro can be skipped completely in the full game after having completed it once, saves do not transfer from the demo to the full game, which means that players would have to go through it twice
We completely understand that some players want to try it out before purchasing, but in order to make a demo that represents the game accurately, we would have to make one from scratch at this point. That is a commitment of time, work and effort that we simply can't justify (making a demo is a lot more demanding than one might think). Sorry about that!
