Walkthrough · Mild puzzle spoilers
The whole journey in order — tutorial, drawbridge, four towers, the transport network, and the milestones on the way to the ending. Structure without spoiling the fun of finding things yourself.
| Phase | What Happens | Milestone |
|---|---|---|
| 1. Tutorial area | The run opens in a guided section of the island that teaches movement and interaction. Solve the short chain of opening puzzles: you will collect a key, shape it to fit, and lower the drawbridge. | Cross the drawbridge — the Big Walk achievement. |
| 2. Out the red pathway | Past the drawbridge, a red walkway carries you out of the starting field and into the open island proper. From here the world is yours: towers can be tackled in any order. | Reach the open island. |
| 3. First camp setup | Near spawn you already passed the paintbrush structure for recoloring segments. Sweep the starting region for tools — walkie-talkies and flashlights earn their slots immediately once night falls. | A tool in every hand and a shared color scheme. |
| 4. Towers in any order | Four color-coded structures — red, blue, yellow, and green — anchor the mid-game. Each asks for five gourd-shaped collectibles earned by clearing challenges, then sends your key on a carving route through five keyholes at its base. | Keys shaped, rewards unlocked (see tower table below). |
| 5. Transport network | Clearing towers reactivates ways to move: the train loop from the blue tower, plus a chairlift elsewhere on the island. Rails and stations were visible from early on — now they work. | Ride the train (Big Ride) and the chairlift (Big Sit). |
| 6. Island milestones | With the map from the red tower, beeline the remaining landmarks: the highest point for the view, the big tunnel under the mountain, and whatever waits beyond the wall. | Big Climb, Big Tunnel, Big Wall. |
| 7. The ending | Big Walk is a hand-crafted adventure meant to be played start-to-finish with the same group, and it has an ending waiting for trekkers who see it through together. | Roll credits as a crew. |
All towers share the same ritual — five gourd-shaped collectibles placed at the top, then a key carved step by step through five keyholes at the base, following the arrows to each next stop. What differs is what each key unlocks.
| Tower | The Ritual | Reward |
|---|---|---|
| Red Tower | Deliver five red gourd-shaped collectibles to the compartments at its top, then carve the key along the arrow-marked keyhole route at the base. | Opens the large blue doorway with red stairs: the map room. Inside sits a giant map of the whole island, and on the upper wall three laser pointers, a compass, and a handheld map you can carry. |
| Blue Tower | Same five-collectible offering and key-carving ritual. It hides on the eastern half of the island, behind the mountain when viewed from the red tower — easy to miss early. | Puts the train back on its rails. Place the finished key in the slot overlooking the tracks and a red train rolls up, ready to board. |
| Yellow Tower | Standard tower ritual. A tunnel runs from this tower toward the blue tower — one of the more useful shortcuts on the island. | Progress toward full island access, with a waist bag waiting in the tunnel route between it and the blue tower. |
| Green Tower | Standard tower ritual. | Its finishing route leads past a supply spot holding both a red backpack and a teal waist bag in one place — the only location that offers two carry items at once. |
💡 Recommended first two
Red tower first — the handheld map transforms navigation for the rest of the run. Blue tower second — the clockwise train loop turns every later delivery into a scenic shortcut.
The complete list, with the shortest path to each. Two late ones are left vague on purpose — they are better experienced blind.
| Achievement | Requirement | How To Get It |
|---|---|---|
| Big Walk | Cross the drawbridge | Unmissable — it ends the tutorial chain. |
| Big View | Visit the map | Step into the map room after finishing the red tower. |
| Big Pack | Wear a backpack | Claim a backpack from any blue spiral-shaped supply building. |
| Big Sit | Ride the chairlift | Board and ride a chairlift once you find its station. |
| Big Ride | Ride the train | Unlock the train through the blue tower, then hop aboard the loop. |
| Big Help | Wear something on your hip | Equip any waist bag from a supply building. |
| Big Climb | Reach the highest point | Head for the island summit — the map makes it easy to spot. |
| Big Tunnel | Enter a big tunnel | Walk the passage beneath the mountain between tower regions. |
| Big Wall | Go beyond the wall | Find the wall crossing part of the island and pass it. |
| Big Makeover | Get shiny | The late-game second way to change color — pursue it once the islands secrets open up. |
| Big Goodbye | — | Tied to the games finale; discovered naturally on the way to the ending. |
| Big Game | — | One of the final surprises of the trek; left undiscovered here to stay spoiler-free. |
ONE RUN, TWELVE UNLOCKS
[ ] Cross the drawbridge (tutorial)

[ ] Wear a backpack + hip item (blue supply buildings)
[ ] Ride the train (blue tower)
[ ] Ride the chairlift
[ ] Climb to the highest point
[ ] Enter the big tunnel (yellow ↔ blue shortcut)
[ ] Go beyond the wall
[ ] Get shiny (late-game makeover)
There is no fixed runtime. The island is built for wandering, puzzles scale with your group, and the host keeps save data between sessions — groups set their own pace from one long sitting to a relaxed multi-week trek.
Any order you like — the game says so itself by letting all four be attempted freely after the drawbridge. Many groups do the red tower first because the map room makes every later trip easier, then the blue tower so the train speeds up the rest.
It is a hand-crafted cooperative adventure meant to be played start-to-finish with a group of friends, and reaching the end is the point: the final stretch and its closing moments are kept as a surprise rather than a checklist.
Nothing appears to be missable. Supply buildings keep their gear, towers wait indefinitely, and transport unlocks persist. If you drop something important, anything held or worn respawns in a pile back at the starting area.
