About the Game

Your Obby Size is a parkour-platformer with a twist: as you race through obstacle courses, your character's size can change, opening up paths and challenges that keep every level feeling distinct. You sprint, leap, and dodge past lava pits, moving platforms, and environmental hazards across a difficulty range that climbs from beginner-friendly layouts to genuinely extreme courses designed to push even seasoned platform game fans to their limits.

The real hook is the combination of size control and exploration. Collecting trophies throughout each course unlocks secret paths, hidden locations, and exclusive character skins, rewarding players who take time to explore rather than just race to the finish. Monsters guard some of the more valuable shortcuts, adding a layer of risk-versus-reward to every run, and sharp-eyed players can find clever routes that dramatically cut their completion time.

Your Obby Size is a great fit for players who love speedrunning, exploration, and a steady stream of escalating challenges. Its rising difficulty curve means younger players can enjoy the accessible early stages while veterans push through the extreme gauntlets toward the top. The game is free to play in your browser with no download or installation required, and it runs well on both desktop and mobile so you can tackle the courses wherever you are.

How to Play

  1. Use arrow keys or WASD to run; press Space to jump (tap the on-screen jump button on mobile).
  2. Navigate each obstacle course by timing your jumps carefully over gaps, lava, and moving platforms.
  3. Collect trophies scattered through the levels to unlock secret paths and exclusive character skins.
  4. Trigger size shifts where prompted to squeeze through tight passages or reach higher platforms.
  5. Watch for monsters guarding shortcuts — lure or sidestep them to safely reach hidden areas.

Tips & Tricks

  • Master the early stages before rushing ahead — solid jump timing makes the extreme courses far more manageable.
  • Collect every trophy you can spot; they unlock shortcuts that save significant time on later levels.
  • Look for subtle differences in the environment's color or texture — they often hint at hidden platforms or secret routes.
  • Experiment with both sizes whenever you have the option; one may open a route the other completely blocks.
  • If a section feels impossible, try jumping from a slightly different position or approaching from the other side.
