No, its listing says it is single-player.

Free in your web browser on echo9.tonnoz.com, the creator's own site. Vibe1Up links to it and doesn't host the game.

No. The prompt on this page is a Starter recipe: our own reconstruction from the game's public listing and live page, not the creator's official prompt. If you made this game, you can share your real prompt at vibe1up.com/prompts/ and we'll show it with the Creator's prompt badge.

Read the full Starter recipe

Build a small, playable browser game inspired by "Echo-9" (Adventure, Simulation).
Concept: THIS IS A 2 DEVICES GAME:

Desktop -> control the pg via WASD
Phone -> Use your phone capabilities to help accomplish the mission (buttons, briefing, accelerometer & more)

You are a delivery guy (think Grab) in a post-apocalyptic Hanoi, Vietnam. You are delivering packages on foot. The grid is out. There are thousands of scooters to avoid while doing so.
Tone/hook (from the game's own page): 2055, Hanoi, Vietnam. The grid.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls: touch controls (tap/drag) that work on a phone plus keyboard and mouse on desktop, shown on a short how-to-play screen.
Players: single-player.
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.
