A complete creature-collector RPG that runs entirely in your browser. No build step, no dependencies, no asset files — every sprite, tile, and creature is generated from code. Your save lives in your browser (localStorage).
You inherit Hollow Manor: one good room, four ruined ones, six soil plots, and a remarkable amount of fog. Bind wild grims into soul jars, grow monsters in your garden, fish ghost-fish out of cursed lakes, restore your haunted manor, climb the endless Soul Ladder, and descend a catacomb that has no bottom.
Open index.html in any modern browser. That's it.
(Or serve it: npx serve . / python3 -m http.server and open the URL.)
Combat is real-time action-RPG, not turn-based: your bound grims fight beside you as a living pack while you move freely, swing your staff, hurl hex bolts, and throw soul jars to capture weakened enemies — all on the overworld map.
| Key | Action |
|---|---|
| WASD / Arrows | Move freely (8-directional) |
| Z | Staff melee · or interact when facing an NPC/object |
| X | Hex bolt (ranged, costs Soul, auto-aims) |
| C | Throw a soul jar at the nearest weakened enemy (capture) |
| Esc / Enter | Pause menu (pack, satchel, gear, skills, deeds, grimdex) |
| In menus | Arrows move · Z confirm · X / Esc back |
- 32 original grims across 11 types (Spirit, Shadow, Bone, Flora, Fungus, Ember, Frost, Venom, Drowned, Moon...), with evolutions and a Grimdex to fill.
- Real-time horde combat — amass a pack of up to 9 grims (cap grows with Necromancy) that fight enemies live on the map. Each species has a combat archetype (chaser, swift wisp, ranged spitter, heavy tank, volley caster). Type effectiveness still applies. Weaken an enemy below a third, then throw a soul jar (3 tiers) to bind it into your pack.
- PoE-style gear — staves, robes, and charms drop from kills and chests with random affixes at three rarities (common / cursed / eldritch). Equip, unequip, or salvage for gold.
- Buildable real estate — beyond the manor, 9 deed plots across the valley, each with its own location buff, upgradeable camp → cottage → hall.
- 5 player skills with NO level cap — Necromancy, Fishing, Farming, Brewing, Delving. Every level grants real bonuses and gates new content (rods, seeds, recipes, deeper descents).
- Farming — grow crops for brewing... and plant monster seeds that hatch living grims. Your Farming level decides how strong they hatch.
- Fishing — a timing minigame at any water tile. Some fish bite only at night; the rarest only under a NEW or FULL moon (sleep to pass days).
- Housing, two tiers of it — first restore the manor's four ruined wings (kitchen → cauldron brewing, study → +15% XP, conservatory → fast indoor plots, crypt → reward chest) as a tutorial. Finishing it unlocks the Deed Book: buy land at SALE posts all over the valley and build it up. Each location does something different — Hunter's Cabin (pack XP), Lakeside Pier (rare fish), Graveyard Ossuary (start catacomb dives deeper), Square Townhouse (shop discount + daily rent), Moonhill Tower (capture + brewing), and more. Every house has its own interior you can decorate with furniture.
- A chain of overworld zones, each strictly tougher — Murkwood (Lv.2-5) → Gravefen → Hollow Hills → Mirkfall → Ashreach → Frostmere → The Pale Summit (Lv.42-50, where the Hollow King roams wild). Fixed difficulty per zone, no level scaling: gear up or turn back.
- Resource gathering — chop gnarled trees, quarry stone heaps, crack wisp-stones for ectoplasm, and mine iron/silver/moon ore veins (gated by the new endless Gathering skill). The shop's forge hammers 3 ore into random gear. Three frontier deed plots join the housing roster.
- Endless catacombs — procedurally generated floors that scale forever, richer chests the deeper you go, and a guardian to bind every 5th floor. The Hollow King waits at B25. The stairs keep going.
- The Soul Ladder — duel an infinite ranked ladder of rival necromancers whose teams scale without limit. A wandering rival also prowls Murkwood daily.
- Day/night and moon phases — encounters, fish, and crops all care what time it is.
