How the game is structured

Summary

In short The game is a straight run from World 1 to World 22, with your progress saved automatically so you can pick up wherever you left off.

When you first load in, you earn the Welcome! badge automatically. From there, you work through worlds in order, earning one badge per world you clear. Finishing all 22 worlds earns the final The end badge. Because progress saves on its own, you never lose ground if you close the game early.

Starting　join the game once and the Welcome! badge unlocks on its own.
Worlds　clear them in order from World 1 through World 22.
Saving　your progress is stored automatically; no manual save is needed.
Completion　clear all 22 worlds to earn The end badge.

Improving your time on the leaderboard

Tips

In short Repeated runs of the same world are the fastest way to climb the leaderboard.

The game runs a live timer and posts your fastest records to a global leaderboard. Up to 20 players can be in a room at once, which gives you a built-in way to study faster runners in real time. Because progress saves automatically, you can revisit any world as many times as you like without losing your overall completion.

Tips worth knowing

Check the leaderboard to see what top times look like on each world before you run it.
Watch other players in your room — seeing a faster line through an obstacle can save you seconds.
Replay worlds you have already cleared; your save stays intact so there is no penalty for grinding.

The met the owner badge

Warn

In short This badge has nothing to do with clearing worlds, so do not expect it to appear through normal play.

Outside the 22 world-clear badges, there is a separate badge called met the owner, awarded for encountering the game's owner and his cat. It has its own unlock condition that is not part of the main course progression.

Worth watching out for

Clearing worlds does not trigger this badge it has a completely separate condition.

The badge description confirms it involves meeting the owner and his cat.

It counts toward your total of 25 badges, so you need it if you want a full collection.

Common questions

FAQ

Does my progress reset if I leave mid-run?

No. The game saves your progress automatically, so you can close it at any point and pick up from the same place next time you log in.

How many badges are there, and how do I get them all?

There are 25 badges total. You get one for starting the game, one for each of the 22 worlds you clear, one for clearing all 22, and one for finding the game owner and his cat.

Can I replay a world I have already beaten?

Yes. Replaying a world does not affect your save, so you can run any world as many times as you like to chase a faster time.
