Sorry, but this is actually pretty boring. You're tossed into a situation with four characters who you don't know, and have to choose between saving them. Why should I know who to save? More importantly, why should I care? Christina and Steve are over-dramatic and completely unlikable. Lionel is obnoxious. Troy has a tragic story but I still know nothing about the guy.
Frankly the game just isn't interesting. It seems to me as if the player is thrown into the climax of a story that should have started much earlier on. I'll also note that the graphics are very minimalistic, with barely anything apart from the character avatars, and the soundtrack is unfitting mostly because I never got to feel for any of the characters. The gameplay was pretty dumb, too. More than once I just wanted to kill everyone off for the heck of it. But there's really no gameplay to speak of. You just take your best guess at a level, which is usually close to what you need to do, and then you restart and adapt your strategy.
The time travel gimmick was interesting and I could see how some might like it, but to me the idea of there being an 'ultimate' ending or 'good' ending takes away from the gravity of your decisions as a player. When all of your decisions end up with you watching a single 'definitive' ending, it just makes the game feel a whole lot less interactive. I would have preferred to have all of the endings jumbled up and know that in the end you could only pick one. Of course, I would also have preferred if this game were a spinoff or sequel to another story, or if it had come with some background information before the events of the game.
