Time Machine: Rogue Pilot doesn't stand out between all the other games that try to make profit from the ever so successful Bejeweled. It's an entertaining game for a short period, but will be forgotten soon.
Put simply, Time Machine Rogue Pilot does too little to differentiate itself which is a fatal shortcoming for an entry into such a saturated puzzle genre. Had it the actual capacity to take us back 20 years, it may have garnered more appeal.
If you just have to have another Bejeweled variant, then I suppose you might want to give the game a look, but otherwise there are better Bejeweled games out there (e.g. the Puzzle Quest games) that are more worth your while.
