Game play itself is fine, but you're constantly bombarded with pop-ups and ads. You have to watch an ad after every level (once you're past the first few tutorial levels) regardless of how quickly you beat the level. I'm perfectly happy to pay a one-time fee to get rid of ads, but the only way to do it in this game is to subscribe to the VIP level which costs the $5/week up to $50/year...just for this one game. I get games aren't free to make, but that pricing is excessive.
