Build Obby World

You gather resources, craft, build and explore. You start on a tiny island and build pieces of other islands to reach new places, slowly turning your world into a big, colorful, happy one full of pets and treasures.

Move with WASD or the arrow keys and jump with Space. To rotate the camera, hold the right mouse button while you move the mouse. That's all you need to start exploring.

Gather resources, then use them to build pieces of other islands. Those pieces become your path to places you couldn't reach from your tiny starting island, so keep gathering and building outward.

Tapping the tiny slimes helps bring the world to life. They're a fun little extra to look out for while you're busy gathering, building and upgrading across your growing islands.

Yes, you can upgrade your character's tools, and then keep upgrading them. It's a big part of the loop, so improving your tools is a good habit while you gather and build.
