Game is heavily pay to progress at higher levels. Don't be folded by early progression. There is a HARD wall at later levels where expensive purchases are insignificant. Updates are few and far between, and the two latest ones over the past 2 months were absolutely useless money grabs. Please I beg you not to spend money on this game. *edit* you have not made a useful update in four months. There are plenty of easy things that could be fixed/optimized. Ridiculous to claim updates are in work.
