Game has fun gameplay and awesome visuals, but everything is wrong with upgrade system. There is no way increase amount of coins, or their value. There is no passive coin magnet (just an unreliable one, flying around). Life upgrade? No, just an empty slot and you have to pay every time you want to fill it. Start upgrade? No, just an ability to buy awesome start every time. If these items are cosumables, why do I even have to pay to unlock them. If you want higher score on Kong, you have to at least make a way to earn more coins.
