The computer partner is the best part of the game - she's so quirky and silly. The story concept is more built around the rewind mechanic - not much to it. The Rewind mechanic, itself, is enjoyably novel for the first few puzzles, but all you have to do to solve the puzzles is think where the cube should be, but in reverse. The puzzles basically solve themselves, even late in the game. It became unrewarding fairly quick.
