Worlds unlock as your jump progression grows
The official description confirms the system, while the game itself remains the place to read each current requirement.
Every normal jump adds 1 Height. Higher jumps earn Wins, trampolines train Height, pets multiply Wins, and trails or auras boost Height. Those systems feed the same progression loop that eventually opens more worlds. Because the public page does not show a world table, this guide does not guess portal costs or copy a list from a similarly named game.
