If you want a quick guide, i don't know where you end up but.
There are 4 signs Walk, Interact (E), Jump, Sprint ,but you only need 3 of them to finish the game -E is next to the market -Jump is in the forest
Tips : Restore the stairs at the spawn and go on top you can see all sign from that view, including the Sprint.
1.Market zone : First one in the loop
- At some point you will hear a phone call stay at the market and the phone will appear. You have to zoom it and then get into the market to interact with it.
Now head to the forest directly.
2.Forest zone :Second in the loop
-After you will hear a Horn, during the horn a boat helm will appear next to the cabin fragment, you will need to zoom it and restore the cabin fragment to get inside and interact with the boat helm.
3.The Lake:
Once both zones are done, head to the lake ,the boat is on the lake down the road to the right of the spawn point. Zoom on the boat to bring it in, then interact with it and go on board.
