I'm sorry, this game was a great concept, but far too short, and poorly executed.
First, the story is flawed straight out of the gate. I don't mean to sound insensitive, but this man researched this time machine for how many years? 22? Is he so pathetic that he can't learn to let go?
Second issue I had was a lack of context. I assumed that the plane crashed because an engine blew out, and didn't realize there was fowl play until I talked to the security guard and saw the 'Terrorist' option. It would have been nice for a news paper in 2021 to mention a bomb on the plane.
Third, the news paper in the cafe was entirely pointless. Not only can you not find the section that was torn off, the news paper also contains no useful text.
Number 4, the bomb. Why would the data pad attached to the bomb contain the terrorist's passenger number, and then conveniently display it after fucking around with the buttons for a bit?
I went into this, expecting to have a Groundhog Day type mystery puzzle, where I had to carefully piece together who done it, and stop them. But really, all it ended up being is a linear game. A big dream squeezed into as little effort as possible.
This had the potential to be one of the greats, but sadly, length and sense drop short, and so does my rating.
Over all, a 3/5 and 4, from me. The game wasn't bad at all, not in the least, but seemed to fall victim to tight deadlines, or lack of imagination. Again, I'm sorry, but I can't rate higher.
