Trees Hate You hides collectible coins and a secret ending across both demo levels. YouTube videos tagged 'All Secrets' and 'All Coins and Chest' have drawn thousands of views from completionist players.
The Steam store description teases hats as collectible items in the full game, and the demo's character creation system already includes hat previews. The phrase 'how to keep the hat' appears in YouTube search, suggesting players want to carry cosmetics between runs.
A secret ending exists in the demo — content creators have published 'Full Game Final Ending & Secrets' showcases revealing what happens when you collect everything.
Collectible chests are hidden in off-path locations that require abandoning the obvious route. The game rewards exploration with coins, but also punishes it with hidden traps near collectibles.
Dying after a pickup should not be treated like a full route reset. Keep routing around the next collectible.
