I really loved this game, until I made a purchase in game to buy a new plane (the steampunk one). I was expecting to enjoy faster game play, but the purchase killed my game. While my tap income became awesome, the offline earnings were never substantial enough, there were no business upgrades to help it other than plugging enormous / silly amounts of money into upgrades, that even my tap earnings couldnt fill (even after hours of tapping.) Fix this poor game design! I'm extremely disappointed!
