Speed….You have to go just the right speed, all your moves must be correct. If you go too slow or too fast, it all blows up. Just follow the map and be on time. Not too early, not too late. If you stay on the timeline, the visitors will "arrive" at the right time…the timeline where the good guys win, gets selected…
Like a mashup of Reverie and Timeless…
