I've reinstalled this on a new phone and been playing for about a week. Sorry to say that his game had gone full on rip off mode. instead of the game rewarding you for passing levels by giving you an advanced set of power ups, you are now hounded by in-game prompts constantly to get you to spend money in order to advance. You can still get some power ups via the daily wheel and completing "quests". They still get a 1 star for making the game much less fun.
