The latest title from Kyle Thompson, developer of popular graveyard keeping, the Crypt Custodian and Islets, has arrived in the form of Well Dweller, a gorgeous looking Metroidvania.
Starring Glimmer, your feathered friend, armed with a matchstick, you’ll need to explore a massive world to find the seven golden feathers to rescue your flock and defeat the evil Queen.
It releases on 22 September 2026 for PC, PS5, Switch 2, and Xbox Series consoles. It’s also available day one on Xbox Game Pass. Why not check out our review?
Well Dweller: Unlock the “A Warm File” Achievement / Trophy Guide
To unlock the “A Warm File” achievement / trophy, you will need to go camping with Ilda. This takes place in The Bog level of the game (yellow area on the map). It might be that this one is entirely unmissable, but I’ve created a guide for it, just in case.
You can watch a video guide below, or read on for a text and image guide.
You’ll start from the tent location in The Bog.

From the tent, head to the left and up into the next room. Bounce on the bubbles to continue going up, into the next room.
Defeat the enemies and then head to the right. In the next room, you’ll need to defeat a large flying insect, then continue right.
In the next room, head to the right and you’ll see a ppool of bubbly water and more bubbles. Throw your matchstick to the wall and use the bubble to bounce to the matchstick. Bounce on the matchstick to read the platform above and into the next room.
In the next room, you’ll meet Ilda who will take you to their campsite. Watch the cutscene and when you wake up in the morning you will unlock the “A Warm File” achievement / trophy.
