Your Obby Size - parkour with changing the size of the hero

You run along an obstacle course and change the hero’s height as you go. With small ones you crawl into narrow cracks, with large ones you can reach distant platforms. Without this change, some routes cannot be completed at all.

There is lava below, monsters walk along the track, some of the platforms move and disappear. Therefore, it is better to inspect the area before jumping, rather than jumping right away. In Obby: Mini-Games VS 1000, the obstacles are divided into short individual challenges, but here the course goes up in one long climb.

Why look for workarounds?

As you progress, you collect trophies. They open secret areas and additional routes, and achievements are exchanged for hero skins. The obvious route up is usually not the most profitable: suspicious cracks in the walls often hide a shortcut.

Speed vs Accuracy

Haste here is punished more often than slowness. The wrong size at the moment of the jump - and you fall down into the lava. Calculating the route is as important here as fast fingers. Where you need a pure race without choosing a path, Escape Tsunami for Brainrots will be closer - you just need to run forward from the water.
