Mournwell

A short room-by-room action game you play in the browser: fight down two depths of a haunted well, pick up relics that change how you shoot, and ring a toll bell that costs you health but hits everything in the room.

Play it: keyboard on desktop, two thumbsticks on a phone. No install, no account.

A chamber on Depth II with two ashmoths and a chimewraith. The bell rings about four seconds in: resolve drops by 15, the shots in the air vanish and every enemy takes 45 damage. Recorded from the dev build in headless Chromium; I used the dev build's test controls to jump straight to that chamber, and a small script pressed the keys.

How to play

Desktop	Phone / tablet	Does
W A S D	left stick	move
arrow keys	right stick	cast in that direction (hold to keep casting)
Space or the TOLL button	TOLL button	ring the bell
Esc or P	PAUSE	pause

Each run starts on Depth I, the Bell Archive: 5 to 8 chambers, one treasure room and the Tollmother waiting in the room farthest from the start. A combat chamber seals its doors until everything in it is dead. Beat the Tollmother and a well opens in the floor; step in and you drop to Depth II, the Drowned Belfry with your relics and remaining resolve, into a new layout and a second, angrier Tollmother. Beat her and the run is won. You can type a seed on the title screen; the same seed gives the same layouts and rewards.

The toll bell. Ringing it costs 15 resolve (out of 100). Every enemy in the chamber takes 45 damage and freezes for a moment, and all enemy shots in flight are swept away. It then needs 8 seconds of silence before it rings again, and it will not ring if 15 resolve would kill you. 45 damage kills a siltling in the first few chambers outright and takes a big bite out of everything else; on Depth II enemies are tougher, so it softens a room rather than clearing it, and against a Tollmother it buys you a breather rather than a win.

Enemies

	Where	What it does
Siltling	both depths	wobbles toward you, then lunges
Wickspitter	both depths	keeps its distance, glows, then spits a three-shot fan
Knellguard	both depths	armoured from the front; lines up and charges, and is stunned if it hits a wall
Ashmoth	Depth II	darts at angles around you; bursts into a ring of slow embers when it dies
Chimewraith	Depth II	fades out (you cannot hit it then), reappears beside you, glows and fires two aimed shots
The Tollmother	end of each depth	three phases: aimed fans, then rings of shots plus helpers (siltlings on Depth I, ashmoths on Depth II), then fast rings

Relics

Eight relics drop from chests, the treasure room and the occasional kill. Duplicates stack.

Relic	Effect
Iron Lament	more damage, heavier shots
Quickwick	faster casting
Longglass	longer range, faster shots
Mudrunner Soles	faster movement
Blackwax Knot	more maximum resolve, and heals the difference
Twin Rune	three shots per cast, then five
Briar Eye	shots pierce through enemies
Compass Moth	shots bend toward enemies
