5 stars: It's surprisingly fun. Very easy, intuitive, has a paywall, but scales well without it.
4 stars: Actually, I was surprised at the fun I am having with this game! It is challenging but not impossible, and I enjoy the retro graphics and music. My only complaints (which are minor) are that you have to unlock hard mode for each level, and that I think the upgrade system is unnecessarily complicated. But both of those things are manageable, and I think this is at least a four star game!
2 stars: this is a game that's old school, absolutely brilliant, easy to play, very addictive... simplicity at it's best!! Alas, seems to have glitches that cost you the rewards you've earned, you lose....play the game, do a mission, use your boosts and not even halfway through, it freezes...and you have to reload, and you've LOST your extra boosts that you've SAVED up for..... including the gold lives!!
2 stars: Edit** since new update game keeps freezing and closing. Usually it's awesome but now I'm not so happy. Love this game. It's like good old fashioned video game fun but better. Pretty awesome. Some levels are a pain but after some time and practice it gets better. Love this game
