Brilliant game! Loved the story and the visuals! Sometimes (especially the boss levels) it gets a bit too hard/random to enjoy but no big deal. It doesnt put you off completely.
A minor bug: It crashed several times when restarting the Missiles level after each failure on iPhone 6 (iOS 9.3.3.)
I think the biggest downside is the playing time. I was a bit surprised when I saw the credits roll after the third boss. Was expecting more levels and the story to unfold even more. So I wasnt fully satisfied and didnt feel like I achieved something when I completed the game.
I must admit that the Challenges dont really add up much to the game. Wish they affectes the original storyline and levels in a way.
