Also, it would be really great if there was a quick demo mode in the game. So it allows you to fast-track the tutorial and go to the more interesting stuff. The length of the tutorial makes sense when playing for private use because you spend hours in it, but to demo it it's a bit boring to go through because people don't have the patience at an event. But it is a really nice experience to try for people. Much more interesting than the usual VR stuff at events.
I had 3 people asking where to buy the game though! And I only showed it to 10 or so. Two of them already had a quest, the other didn't (so I doubt it'll convert to a sale, sorry, but still..).
