How Do You Open StarDoor With All Walls Intact?
Unlock the Worm achievement without starting a fresh save by using Hole and Bibble to reach StarDoor while every wall remains intact.
You do not need to erase your save. Attempt Worm after a Rewind: earn enough Star Orbs for the Star Key without breaking any wall, buy Bibble, then use Hole + Bibble to travel under each wall section and open StarDoor while all walls are still intact.
Before you start the attempt
- Rewind so the world walls are restored.
- Do not damage any wall after the new run begins.
- Earn enough banked Star Orbs to buy the Star Key.
- Buy Bibble before trying to cross below the wall boundaries.
Exact Worm route
- 1Place Hole near the wall boundary without hitting the wall.
- 2Use Bibble while positioned over Hole to descend and move beneath the wall section.
- 3Repeat the under-wall movement for every barrier between the office area and StarDoor.
- 4Return to the surface near StarDoor, use the Star Key, and open it before breaking any wall.
What invalidates the run?
Any wall damage can invalidate the “all walls intact” condition. If a wall cracks or breaks, stop the attempt and Rewind again rather than continuing to StarDoor.
Hole + Bibble troubleshooting
Bibble throws me past the safe landing
Use shorter movement inputs and align Hole closer to the wall before activating Bibble.
I fall out of the route
Reset position without touching a wall. If recovery damages a wall, restart the attempt after another Rewind.
StarDoor will not open
Confirm you actually purchased the Star Key and that no wall was damaged during this run.
FAQ
Does Worm require a brand-new save?
No. The playtester guide states that it can be completed after a Rewind, which restores the walls for another attempt.
Can I break one wall and still unlock Worm?
No. The achievement requires opening StarDoor with all walls intact, so treat any wall damage as a failed attempt.
Why do I need Bibble?
Bibble and Hole provide the movement needed to pass under wall sections without breaking them.
