1. Measure a baseline
Record starting progress, clean for a fixed number of minutes, then record current progress.
Clean all the leaves Progression Guide
Follow the confirmed clean, upgrade, unlock, and 100% loop while measuring choices from your own run.
Quick answer
Clean, upgrade, unlock, repeat
Cleaning advances visible progress. Tool upgrades are meant to improve the run, map unlocks open more cleaning space, and 100% leads to the Secret Ending. Exact upgrade costs and hidden formulas are not claimed here.
2. Buy one upgrade
Change one variable at a time so the result can be compared fairly.
3. Retest the same way
Use the same sample length and similar route; compare percentage points per minute.
4. Follow map unlocks
Check newly accessible space when progress slows, then continue toward 100%.
Decision method
Compare measured gain
Use the upgrade decision board to rank before-and-after tests. Use the pace calculator to translate a sample into an ETA.
When progress stalls
Check visible space first
Sweep edges and newly unlocked areas, then take another timed sample. If progress still moves, the run is slow rather than frozen; if it does not, revisit boundaries before restarting.
