About Your Obby Size: Parkour, Size Control, and Secrets

Your Obby Size blends parkour with a size-changing mechanic, sending players through a gauntlet of obstacles that range from easy to extreme. The goal is straightforward — reach the end — but the path is packed with lava to dodge, monsters guarding certain areas, and hidden shortcuts waiting to be discovered. Collect enough trophies to unlock secret paths, access new locations, and earn unique character skins. Show everyone you're a true parkour master.

How to Play Your Obby Size

The objective is to make it all the way to the finish. Along the way, avoid lava and conquer increasingly difficult challenges. Changing your size with the dedicated controls is central to navigating obstacles and finding routes others might miss. Trophies collected throughout the run unlock secret paths and new locations, while certain areas are guarded by monsters that must be avoided or bypassed. Keep an eye out for shortcuts that can carry you closer to the top.
