Well Dweller Post Game: What Unlocks After the Credits

Most metroidvanias end when the final boss falls. This one leaves a drawer open. The best window we have into what sits behind it is a labeled 100% playthrough that rolls the credits and then keeps playing for a long stretch, picking up quests, a fresh movement trick and a marked-up map. This page walks through what that run documents, and is just as clear about what it cannot.

What is there to do after the credits?

A recorded 100% run shows real post-credits content: an NPC who wants a sealed castle door opened, a challenge from rescued siblings, a kingdom map with five locations circled, and a movement ability handed over after the ending. Everything below comes from that single run, so treat the details as player-reported rather than official.

The shape matches the developer’s history. The same runner notes that in Crypt Custodian “there was stuff to do after you got the ending,” and expects the same here - then spends the next stretch of footage proving himself right. It also matches the timing pattern in our achievements guide: one completionist was still finding post-game NPC quests more than ten hours into the game, long after the credits he describes as satisfying.

Which quests open up after the ending?

Three post-credits finds are documented in that single run: a castle door quest, a circled map, and a diving-board dare. None is officially listed anywhere, and we only know what the run’s subtitles capture, so treat the trio as the shape of what exists rather than a complete list:

The castle door plays out completely on camera: the door opens, the treasure room is looted, and the coin lands in your pocket with its discount text read aloud. The circled map does not resolve in the footage we reviewed - the runner never shows what the five spots hold - so we will not guess for you.

What changes in the world after the credits?

At least two things, both from the same run. First, the queen’s chamber closes: coming out of the ending, the player tries to walk back in and reports that he cannot. Second, Glimmer gains a movement gift - a move he works out loud as slamming the ground and holding jump to soar.

The gift answers a complaint the run makes before the finale: he was one ability short and wondered whether it would arrive as “an after credits roll thing” - it did. The castle hides a third change of a quieter kind: a tattered storybook telling of a kind witch who sheltered the kingdom’s birds from the queen’s feather levy until a spell gone wrong turned her flock to stone and shattered her own soul across the land. The runner’s read is that reassembling that soul is what the post-game asks of you - his speculation, worth flagging because it rhymes with the spirit-collecting track in our collectibles guide, but speculation all the same.

How does the post-game feed a 100% run?

The post-game is where completion actually happens. The in-game second map flags every collectible you have missed, in-game tasks keep paying out - collect ten trinkets here, upgrade all of your trinkets to the maximum amount there - and one completionist revised his own estimate from ten hours to about fifteen once his real pace was on the clock.

A sensible order, built from the recorded habits:

1. Finish the sibling rescue and see an ending first - the rescue gates the finale, and the chamber may not reopen afterwards.
2. Take the true ending chase seriously on that same save; our true ending guide separates what is confirmed about it from what is not.
3. Sweep the backlog with the second map, then spend surplus currency on the last trinkets and upgrades rather than hoarding it.

What can’t we confirm yet?

Quite a lot, and we would rather list it than guess. Whether the five circled locations ever open, whether any post-game quest feeds the trinkets collection or the true ending, whether the coin discount really applies to everything, and whether anything carries into a fresh save are all open - no second source covers them yet.

The single-source caveat matters more here than anywhere else on the site: every claim on this page traces to one player’s upload. If a patch note or a second 100% run documents the post-game differently, this page updates with a fresh date. Until then, treat it as one thorough traveler’s itinerary, not a tour guide’s guarantee.
