Killed by developer greed. This game has the potential to be good but there is no way to permanently remove forced ads. Instead the developer has you buy a number of tickets that gets you out of so many ads before the ads resume. I would be likely to play this game for years if it wasn't for this greedy tactic. And even if there was a way to fully opt out of advertising, the developer wanting $5.99 to get out of ads (temporarily) is absolutely insane. I could see paying a $1.99 at most.
