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.
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.
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.
