Game is highly addictive and fun, I do find that its VERY pricy on the pay to win side if you do decide to buy into the game, but for any free players, you'll start off kicking butt leveling up, unlocking and upgrading, but then like most "pay to win" games, you eventually hit a "im stuck on this level" or "now I can't proceed without basically having to make a purchase"...... overall, just keeping it honest, like the game enough to purchase, but some of the packs NEED TO BE AFFORDABLE! PLEASE!

I really enjoy this game, enough so that I was nonplussed about the adds because the game is fun and they are MOSTLY ones you can do for extra stuff and not tied to level ends. I haven't spent any money on it, was grinding away happily. I was stuck at lvl 24 and then lvl 20 on binary. That's fine, I can grind some. Then as Michael S. mentioned in his review... it suddenly got harder. Levels I was grinding on I can no longer win. Levels where I perfect cleared every time I can no longer do so.

I did enjoy the game a few months ago but for some odd (cash grab) reason, they turned the difficulty setting up and I mean WAY UP! we went from clearing multiple levels a day to being lucky if we clear one in weeks!! it feels impossible to go back and replay levels you've already completed which is crazy. this quickly went from fun and exciting to frustrating and conflicting. seeing as they dont care about user experience and just want money, I dont see this lasting for me.
