Win to Build Obby
The two-phase game loop
Step
The game runs on a simple but satisfying loop. First you attempt the current obstacle course and try to reach the goal. Once you finish, you get to help construct part of a new obby — so the same session puts you in both the player seat and the builder seat.
- Attempt the obby work through the current course from start to finish.
- Reach the goal crossing the finish is what unlocks the next phase.
- Join the build after winning you take part in putting together a section of the upcoming course.
- Watch it go live the stage you helped build becomes what other players have to beat next.
