A Roblox obby is a game that challenges players to navigate through a series of obstacles to reach the end of the level. Obstacles can include platforms to jump across, walls to climb over, and traps to avoid. The game typically features checkpoints, which players must touch to save their progress in case they fall or fail an obstacle. Obbies can vary in difficulty, with some being relatively easy and others being very challenging. Some obbies may also include power-ups, such as speed boosts or extra lives, to make the game more fun and engaging. The game is played from a third-person perspective, with the camera following the player character as they navigate through the obstacles. Players can customize their character's appearance, which can include choosing different clothes, accessories, and hairstyles.
