Great game, i play a few hours almost every day, the game never fails to amaze me, i once beat a person with 15 power boxes while i had none, it justs showing that skill is relevant in this game, you don't have to pay to progress, it does speed it up but you can still have a ton of fun without money, so for any free to play players i highly recommend, no complaints by the way would bump it up to a 5 star if there was a little more for the free to play people. Overall 10/10 reccomend, good job.
