The secret ending
What unlocks it, what we can confirm, and what we are not going to invent.
What the developer says
The game's own description is explicit: reach 100% by cleaning all the leaves to uncover the truth, and hitting 100% unlocks the secret ending. That is the requirement, straight from the experience page — not a rumour.
There is no shortcut in that sentence. 100% means the whole map, which means every unlockable area, which means the upgrade path is the real gate.
How to actually get there
- Prioritise bag capacity so clearing is not interrupted
- Unlock new map areas as they become affordable rather than over-upgrading in an area you have finished
- Treat the completion percentage as the score, not cash
What we will not tell you
We are not going to describe the ending itself from second-hand posts. The community wiki's pages on The House and the Vent are currently empty, and we would rather have a short honest page than a long invented one.
When there is a sourced account of the ending, it goes here with a date and a link. If you have reached 100% yourself, tell us and we will credit it.
