It would be on for a few seconds and then it would close on its own because I left it running assuming I'd come back to it 30 minutes later. I found a solution: Shut down entirely instead of simple restart. Once I did that I was able to finish the game so far.
I really should give a review already: This is the best game I've seen in this category. There's a story, it's not super cheesy, and I like both the main two girls as well as the cafe. Other games have something broken about them or some such that I can't turn off certain things that don't interest me. You and the team thought of everything, so I feel at peace playing Project Reality. Can't wait to see what the update brings!
