The hill climbing racing is one of the oldest android game in playstore.
The graphics are good and game allows you to use different types of cars with different types of maps.
The game is totally balanced and offers you unlimited path in each map.
The game works on almost every handset without any lag.
The controlling car is easy and a very simple layout .
The concept of game is very good about the maps , that each map varies in gravity, surface texture , road condition etc. Allows you to use specific drive for different terrain.
The only change I want is characters they can be more real.
