The nine trials
Each universe holds nine of them, played back to back. A fall doesn't end the run: it costs you time.
Nine trials, one guardian, one portal. The rule fits in a sentence; everything that follows lives in the detail of the clock and the validation of each run.
The principle
Each universe holds nine of them, played back to back. A fall doesn't end the run: it costs you time.
At the end, a boss unique to the universe. Three phases, a pattern to read. You don't wear it down, you learn it.
Beating it opens the next universe for good. An open universe stays replayable so you can improve your time.
The clock
Fair play
Every time is recalculated server-side from the game trace. What the app reports is never taken at face value.
A modified client, an input emulator or a bot invalidates the run and suspends the account.
One player, one account, one nation. Secondary accounts used to inflate a national ranking are removed from the total.
No purchase, item or option alters the game's physics or the way time is calculated. The leaderboard rewards the run and nothing else.
