GRAVITY DOG is a runner in which the player is able to control the force of gravity (change the gravity up and down). The goal of the player is to run as far as possible, and it is desirable to get a better result. The visual design of the game was designed in minimalism. The entire game world is generated from pre-prepared sections of tunnels. In this game, the key role is played not only by the skill of the player's dexterity, but also by his luck. Tap the space bar to change the gravity!
