iOS game prototype #2

Type: 3d, iOS Game engine: Unity Device orientation: Portrait Gameplay: The goal of the player is to escape from the police pursuit. Behind the player's vehicle is a police car on the signal. The player is the driver of the vehicle and he must turn on the next supercharge of the vehicle in a timely manner by tapping when the needle in a gauge is on the appropriate field. The supercharger indicator is divided into three zones: two yellow zones, a normal 100% supercharge and red between the yellow zones a hyper-boost of 150%. The location of the supercharging zones changes with each next use of the recharge. The player at the beginning of the game starts with a certain number of supercharge = 1 (during the game the player may increase the number of supercharges by buying a +1 upgrade).
