Read the full Starter recipe

Build a small, playable browser game inspired by "Heartjack" (Action, Strategy).
Concept: A Stylized Melee PvP.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls: keyboard and mouse on desktop, shown on a short how-to-play screen.
Multiplayer: the original is listed as multiplayer. Start with a local or bot opponent, then add online play (e.g. WebSockets) once the core loop is fun.
Core loop: include progress saved in localStorage.
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.

Remix notes (our suggestions, not the creator's)

Heartjack is described as a stylized melee PvP game, built in Three.js and tagged Action and Strategy, and it's multiplayer. Melee PvP is all about reading your opponent: spacing, timing and the moment they commit. A strong art style makes those reads clearer. Remix idea (our suggestion): keep one-on-one melee but add a strategy layer before the fight. Pick a card, a stance or a weapon that counters your rival, rock-paper-scissors style. Or make the arena itself shift during the match so position matters as much as reflexes. Prompting tip: ask your AI tool for clear attack wind-ups, visible hitboxes in a debug mode, and a short hit-stop on contact. Start with a local two-player mode to tune combat, then add online play. Melee feels fair when every attack can be seen coming, so prompt for readable animations first.

Publish it, then polish later

host it free on Netlify. Once the core game works, optionally add voice or sound with ElevenLabs or 3D assets with Meshy. Netlify, ElevenLabs and Meshy are affiliate links; we may earn a commission at no extra cost to you. None of these extras is required to build the core game.
