Quality checks and fixes for a game that already runs, on any engine or platform. It covers the parts of a game that are not features: how the controls feel, whether the numbers are balanced, whether the same input always gives the same result, whether the UI fits every screen and input device, whether the sound plays on every browser and phone, whether a new player understands what to do, and whether the text works in other languages. It also ships an in-game panel for changing values while playing, instead of another edit-and-rebuild round. Published by NEXPACE alongside the MSU builder skills.

audio-checkChecks, repairs, or sets up a browser game's audio: its sound settings and whether sound actually plays under each browser's conditions. Use when a game is silent, or goes silent, on a phone, in Safari, inside an iframe or an in-app browser while it plays elsewhere; when sound works for the builder
balance-tuningReviews and tunes game balance across difficulty and progression curves, session pacing, option or strategy trade-offs, and reward economies. Use when players report that a game is too hard, easy, short, long, or grindy; a weapon, upgrade, or strategy dominates; damage, health, spawn, drop, price, o
cross-device-checkAudits a game's UI and interaction across supported viewports, aspect ratios, pixel densities, orientations, and input capabilities. Use when mobile, tablet, desktop, controller, keyboard, pointer, or touch support is being checked; UI clips, overlaps, blurs, or overflows; controls are unreachable o
debug-visualizationUse when creating any game or interactive toy, when adding gameplay/UI features to one, when the builder asks for value tweaks in any language (too fast/slow, too big/small, a bit more/less, move it left/right/up/down, can't hit it, my tap doesn't register, hitbox, feels floaty/heavy/off, easier/har
determinism-auditAudits nondeterministic game behavior and flaky execution. Use when the same initial state and inputs produce different outcomes, a test fails intermittently or only under load, behavior differs by frame rate or machine, a replay diverges, or lockstep peers desynchronize. Establishes the required de
game-feelUse when a game's controls feel stiff, floaty, heavy, slippery, unresponsive, or unfair; when players miss jumps they thought they made, snag on platform corners, lose inputs pressed during another action, or get hit by grazes; when a platformer, runner, or action game is being built or polished and
game-tutorialAudits, adds, or reworks a game's first-time-player tutorial. Use when players cannot identify the controls, goal, failure conditions, or a non-obvious rule; new players quit before completing the core loop; onboarding presents too much at once; or an explicit tutorial or first-run improvement is re
i18n-setupSets up or repairs localization for a game: player-facing string extraction, locale catalogs, draft target-locale translations, fallback and locale selection, runtime switching, plural and parameter formatting, glyph coverage, and translation-safe layouts. Use when the user requests another locale o
Skills and an MCP server for building on MapleStory Universe game data. The bundled maple-lookup MCP server searches the MSU Open API for characters, mobs, maps, skills, items, and sprites; the skills cover how that data is structured, how to choose between candidates, and how to turn it into something that renders. This plugin owns the MSU Builder OpenAPI key, and other NEXPACE plugins build on it instead of copying its skills.

A Claude Code status line for MapleStory Universe builders. It reads the MSU Builder notice board and keeps the newest notice under the prompt as a clickable link, so an announcement about maintenance, an API change, or a deadline arrives without leaving the terminal. Segments are toggled individually and it wraps an existing status line rather than replacing it. No credential required.
