Zork v1.0.5

The compass now agrees with the house grounds: facing the white house from West of House reads east. A wider field opens the approach to the house, and the title screen previews the same meadow and house seen during play.

The rainbow now crosses a visible gorge to a separate far landing. The terrain and walking boundary follow the gorge's rim, making the route's geography clearer.

Existing expeditions retain inventory, puzzle progress and orientation. Saves positioned over the new gorge are returned to the existing near bank; safe saved positions stay in place. The compass correction changes displayed bearings without rotating rooms or doorways. Previous releases remain available.

Validation: 77 tests, TypeScript checks and the production build passed. The gorge and far shore were inspected in the rendered game, with title-screen checks at desktop and phone sizes.

Zork 1.0.4

Doorways now respond when you stand close to either side of the opening. The coal mine has a recognizable gas-filled side working, with separate signs for the freight basket and personnel passage. The vampire bat has a clearer hanging silhouette, and the gold coffin opens visibly with its sceptre inside.

• Doorway reach also covers the house window and mirrors while retaining their opening requirements.
• The coffin lid slides aside and keeps its open pose after saving and reloading.
• Existing saves, inventory, solved puzzles, arrival positions and challenge rules remain compatible. Earlier releases remain available.

Validation: all 71 tests and the production build pass; desktop and phone-size browser checks, ten older saved expeditions, and the extracted Windows package were reviewed.

For Windows, download Zork-Windows.zip, extract the complete folder, and open Play Zork.cmd. The source archives require Node.js and npm.

Zork 1.0.3 - Deliberate item use

Item-use puzzles now ask you to choose something from your satchel. Examine the obstacle, read its description, and try a carried item. Wrong choices are harmless, and you can step away and return later.

This applies to the leaking pipe, vampire bat, locked grating, dome railing, songbird, dam bolt, folded boat, sand drift, rainbow, egg clasp after defeating the thief, pressure mill switch, and gas passage. The shaft basket also asks before lowering its supplies. Spoken-answer puzzles retain their existing text entry.

Saved expeditions remain compatible, and completed puzzles stay solved. The item picker supports keyboard, mouse and touch, with readable portrait and short landscape layouts.

Validated with 61 tests, 41 saves generated by the published v1.0.2 game, desktop and mobile browser review, and Windows/Linux CI. Older releases remain available, and previously published web bundles are retained for open game tabs.

Zork 1.0.2 — bat and sand prop polish

The bat's roost was falling back to a generic treasure ornament, and the Sandy Cave's sand drift used a stone pedestal. The roost now has a hanging vampire bat attached to the mine timbers; the sand is a low drift that visibly changes after digging. Both follow the existing puzzle progress when a saved expedition is loaded.

The model audit covers every campaign prop, held item and trophy miniature, including props selected after puzzle progress. Missing model types now produce a diagnostic instead of a misleading ornament, and regression checks prevent them from slipping into a release.

Existing save format, inventory, puzzle rules, interaction locations and collision layouts are preserved. The web release retains earlier hashed game assets for pages that are already open.

Validation: 54 passing tests, production build and typecheck, independent visual review, normal keyboard/touch interactions and save/reload checks. Phone layout was checked at 390 by 844 in a desktop browser.

Play at https://zork-underground-empire.netlify.app/ or extract the Windows ZIP and open Play Zork.cmd. Source and original notices remain included under their existing licenses.

Zork 1.0.1 — Dam and maintenance polish

The maintenance-room leak now sprays from a damaged joint in connected pipework, with falling droplets and a wet floor. Repairing it stops the water and leaves a visible putty seal.

The dam's square control bolt, green indicator and pressure gauge now sit on a floor-mounted iron stand. The maintenance panel has four physical colored buttons.

Existing expeditions can continue without restarting. Save format, puzzle progress, inventory, checkpoints and collision layouts are unchanged. The previous game bundle and v1.0.0 downloads remain available.

Verified with 51 passing tests, 17 saves from the original release, desktop and touch-layout review, and an original save imported through the production game's menu.
