Remix: Rift Survivors

Build a small, playable browser game inspired by "Rift Survivors" (Action).
Concept: Cyber-neon hack-and-slash roguelike with Demon's Souls-style combo, parry, and stamina. 100-floor cycle, 3 boss types with multi-pattern attacks, MMO-like equipment rarity (Common→Legendary), and skill chains. Auto JA/EN locale.

(日本語)	デモンズソウル風コンボ・パリィ・スタミナ管理を採用したサイバーネオンのハクスラ系ローグライト。100階構成、3種ボス × 5〜6攻撃パターン、レア度装備 (Common〜Legendary)、スキルチェイン。日本語/英語 自動切替。.
Tone/hook (from the game's own page): Cyber-neon hack-and-slash for Vibe Jam 2026.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): WASD to move, tap on mobile. Show them on a short how-to-play screen.
Players: single-player.
Core loop: include a visible score, levels, stages or waves that ramp up, progress saved in localStorage.
Audio: add simple sound effects and music (start audio on the first click/tap).
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
