How to play PrismCraft

To play PrismCraft, open https://lairhisson.itch.io/prismcraft and click Run game for the HTML5 build in your browser, or download Build Prismcraft 0.3.zip. These unofficial steps do not list controls—keybinds are not verified here.

Play on itch.io

Open the official itch.io page

Go to https://lairhisson.itch.io/prismcraft. That is the only official playable build this unofficial guide points to. Do not download a zip from a mirror or an unofficial host.

Browser (Run game) vs zip download

itch lists PrismCraft as HTML5. On a desktop browser with WebGL, click Run game to play the prototype in the page. You can also download Build Prismcraft 0.3.zip from that same official itch page if you want an offline package. Mobile play is unverified here.

What you need

Verified from the official itch page: Prototype, HTML5, three.js. It is not a Mojang product. No official RAM or GPU floor is published. Use a current desktop browser with WebGL. This unofficial guide does not invent keybinds.
