Two major gripes: first, the game gets ridiculously difficult after the first 8 or 9 missions. I mean Im all for a challenge, but you basically have 0 chance of survival or of saving your friendlies during the dreaded "protection" types if missions. (The WORST type of game missions ever conceived BTW). This games quickly goes from being very fun to extremely frustrating, ruining a otherwise great game. If there was better or more life, this would have been a more enjoyable experience. Also, the developer has simply stopped updating this game back in 2011. As a result, the game is based on old iPhone technology (made for iPhone 3GS) and is NOT retina screen-compatible. Even after Apple mandated that developers at least update apps icons to retina, this developer ignored, and the iBomber app icon is all pixelated and hacked on iPhone 4S. Developer has basically quit on this app, so dont expect any future upgrades or updates. Pretty lame. (Buy this at your own risk. Youve been warned.)
