The video shows a person playing a game on a mobile device. The game appears to be a side-scrolling platformer with a character running through a forest-like environment. The character jumps over gaps and avoids obstacles, such as trees and rocks. The game's graphics are colorful and cartoonish, with the character and environment rendered in a 2D style. The character moves fluidly, and the game seems to be responsive to the player's touch inputs. The game's interface includes a score counter and a star counter, indicating the player's progress and performance.
