The Lonely T-Rex, a tyrannosaur that moves relentlessly from left to right over a desert with just two colors—black and white—is controlled by the player in Dinosaur Game. The user will have to jump or crouch over obstacles like pterosaurs and cactus while traveling. The dinosaur will "jump" instantly if the user hits space on the keyboard or makes touch with it on a mobile device; otherwise, it will "crouch down." The speed of the game will gradually go up. The game will end suddenly when the lonely T-Rex character runs into any obstruction.
