Practical Guide
Game is fun to start, but at later levels becomes annoyingly frustratingly difficult unless you spend money on boosters. I would have to play a level 20+ times and just get lucky to get past it. At that point it's no longer fun, so I uninstalled. I just can't afford to blow money on a mobile game. (And I wasn't going to review but I keep getting ads asking me to come back. I do miss the fun parts but not the frustration)
