To start the game, you need to press the spacebar or the up arrow. The same buttons are used to jump. You can crouch using the down arrow. On mobile devices, all you need to do is touch the screen.
The player's task is to score as many points as possible. The speed increases over time, and the days will change into night. Dinosaurs are waiting for obstacles that you need to dodge.
If the player accidentally encounters them, they will automatically die and the game will restart. And so it goes in a circle.
