Ok, so this game is actually a lot of fun; I'm so glad they gave it away this month. Once you get the hang of the controls they're actually not so bad. Also, if you're stuck on a level I found that what you should do is just pay 10,000 coins for an awesome wingman and he'll not only get you through the level but you'll basically double the score of everyone on your friends list. Also, it's crucial to make sure you use the right skills for what enemies are in each level. They show elements for a reason.
Anyway, awesome game. Having a lot of fun with it.
