I dont mind games with in app purchases as long as they arent mandatory. However, limiting the time that someone can play your game via a time limit without making a purchase is just ridiculous. This doesnt encourage me to play your game, but it does encourage me to move on to something else and tell others to avoid your app. Theres many better tower defense games out there without these issues. For instance, check out the Kingdom Rush series instead where the game play is better and there are no forced purchases 9only optional ones that arent needed). Money grab models like the one used in crazy kings are what ruin the App Store. Vote with your dollar and avoid this one.
