Timesville Secret: Fish Key, Windowed Safe, and Brain Scan

Short answer

Reveal the fish paper by scanning the beach, fill its 18 silhouettes, leave the pole and collect the key. Progress to the house beyond the waterfall, enter its smaller room, press Alt+Enter so the wall safe exists instead of a black hole, and unlock it. Follow the dead-town/memory sequence to the graveyard, then select two brain holes that show the same life event at different ages and press the large button; repeat until the angel says 'Enter.'

When to do it: Before fighting or avoiding Chameleon and before Timesville closes. Prepare the route on the late Chapter I backup used for Ending C.

What you need: Metal detector, fish paper, all 18 fish, the paper's key, waterfall-house access, windowed mode, and the brain-scan matching logic.

Missable or risky: Yes. The key and safe route must be completed while Timesville remains accessible, and the safe may be invisible in full-screen mode.

Confirmed details

The metal detector reveals the fish paper on the beach. Its silhouettes track the 18 named catches across Day 1–3 and Night 1–3, and the completed paper supplies the old key.

The secret destination is the smaller room in the house beyond the waterfall, associated with the normal microwave/shared-room progression. In full screen the wall can show a black hole; in windowed mode the usable safe appears.

After the safe, the route presents a dead version of the town and a graveyard scan. Each selectable hole plays a memory; pair two that represent the same action across life stages, such as a child and an older person blowing out candles, then press the large top button.

This page separates documented requirements from route advice. Names, achievement conditions, platform details, and item counts are checked against the linked Steam records; navigation is cross-checked against recorded gameplay. If an update changes a room, prompt, or trigger, use the verification note below before assuming the save is broken.

Step-by-step solution

Step 1 — Scan the beach to recover the fish paper and use it as the checklist while catching three unique fish in every one of the six clock states.

Step 2 — Leave the fishing pole after the final catch, wait for the achievement, inspect the completed paper, and take the key as a separate inventory pickup.

Step 3 — Continue normal Timesville progression until the waterfall house is accessible. Enter the smaller interior door and press Alt+Enter to switch the game to windowed mode.

Step 4 — Use the key on the safe that appears on the wall. Follow the resulting butterfly/dead-town sequence and continue to the graveyard instead of assuming the black-and-white return is a softlock.

Step 5 — In the brain scan, open one memory, find the corresponding event on the other side, select both, and press the large button. Repeat the pairing process until the final 'Enter' prompt and complete the return scene.

Common failures and softlock risks

The fish achievement does not automatically put the key in inventory. Inspect and click the completed paper after leaving the pole.

The safe can be replaced by a black wall opening in full screen. Use Alt+Enter before declaring the room broken.

The brain puzzle matches event pairs, not adjacent holes or identical character ages. Watch both clips and compare the action.

Recovery rule: stop before crossing another chapter boundary. Confirm the current objective, cycle every usable inventory item, and retry the interaction from a clean room entry. If the trigger still fails, close the game before restoring a known-good save; copying or replacing live save files while the game is open can overwrite the recovery state.

Version and verification

The route was checked against the fish Steam guide, the all-endings guide, the Timesville secret video around 07:49, and surviving player reports describing the safe, dead town, graveyard, and paired brain memories.
