Ok the truth is it's not that great a game. But you don't have to throw it to the trash just for not being amazing!
Which brings me to the next subjetct: the powers. Slowing and stopping time are useful for the obvious reasons , (ok maybe one or two puzzles). But Reversing time really has little use when fighting.
Weapons was the other thing I liked. I think,(even though it may sound stupid) that in shooters the weapons have to have the right feel, and a little more. You need to feel like you're holding something dangerous.
The graphics and sound were mediocre-to-good but generally indifferent.
Finally,the scenario was kinda blurred with fancy time-jumps,but the essence was the typical evil-genius-steals-super-weapon case. I would have liked a different,more unexpected ending.
My point is that if you asked someone how'd he/she liked the game, he/she would've shrugged their shoulders and said something like: "It was fun,i guess..."
