The Nocturne Puzzle Boy minigame, expanded. Best with your own copy (the Classic theme); plays out of the box with the bundled Default theme.

Title, with the original Jack-o'-Lantern	Stage select and the Classic campaigns	In play: the original HUD and prompts
The original menu, with your moves and time	A bonus stage the original never plays	Every control, in the original's style

_{Classic theme images are rendered from a local copy of the game and hosted as uploads; none of it is in this repository or its downloads.}

Push blocks, turn swivels and fill holes to reach the goal, with the minigame's rules, a campaign of new stages, a level editor and level packs. If you own Shin Megami Tensei III Nocturne HD Remaster, import it once and every stage plays in the original's look and sound: its board, its Jack-o'-Lantern, its camera, its music. Without it, the Default theme plays the same stages with Pixel Jack, a pumpkin in a witch's hat, and art and sound made for this game. It needs no Steam and no network either way.

Status: 0.1.0 is out for Windows, Linux and macOS. The Nocturne-styled interface for the Classic theme comes in the next release. See ROADMAP.md and CHANGELOG.md.

Features

• Twenty original stages, from a first walk to the goal through blocks, holes, swivels and a team of up to three Jacks, each with a hint on the help screen.
• Push blocks, turn swivels and fill holes with the same rules as the original, from puzzle-boy-engine.
• Stage select with cleared, new and locked stages, your best moves and time, and a preview of each stage.
• A level editor: paint a stage, see every problem by its cell, playtest it, ask the solver, and keep it under My Stages.
• Level packs: export your stages as a .zip to share, and import other players' packs, each checked before it's added. See docs/packs.md.
• Progress and settings saved on your computer, with a backup if the file is ever damaged. No account, no network.
• Settings for fullscreen, window size, UI scale, music and sound volume, mute, reduced motion and high contrast.
• Keyboard, mouse and controller. Undo, restart, a turning camera, an overhead view and the original's scroll mode.
• The Default theme's graphics are drawn and its music synthesized in code: nothing to download after you unpack it.
• The Classic Nocturne theme, from your own copy, for every stage: the campaign, your own, imported packs, and the original's 20 stages and 23 unused bonus stages.

It plays on puzzle-boy-engine, the rules shared with puzzle-boy, a preservation port that reads the original stages from your own copy of Nocturne.

The Classic Nocturne theme, from your own copy

Import once: Settings → Classic Nocturne → Import from My Steam Install (or Import from a Folder or Zip, with the folder that holds smt3hd.exe) copies the eight bundles the theme reads, about 120 MB, into a classic pack in your data folder, and checks each file's hash whenever it's used. The Theme setting is Auto: with a pack it plays the Classic theme, without one the Default theme; Classic and Default fix it. The whole interface follows: in play the original's HUD, controls bar, menu and rules page, and on Community's own screens the original's font, windows, cursor and key prompts, with the Jack-o'-Lantern on the title. Stage select also adds Classic: Original 20, the original's stages in its order, and Classic: Bonus, 23 unused stages from the game that a solution clears. The Manikin Kid and the original's dialogue aren't part of it.

Export My Classic Pack writes one zip you can import on your other computers. It's made from your own copy, for your own computers: don't share it. Nothing from Nocturne ships with this game or is downloaded, and the game never looks for Nocturne unless you ask. Remove Classic Pack deletes the pack again, keeping your progress. From a command line, --import-classic <game folder or pack zip> and --export-classic do the same.

Screenshots committed to this repo use the Default theme only; the Classic images at the top are hosted uploads.
