How to play Bruna Worlds games in VR on Meta Quest

1. A web page that opens into VR

WebXR is the part of a web browser that lets a page open into virtual reality. The Meta Quest Browser supports it, so each game is simply a web address: no store, nothing to install and no account. You open the page, press Enter VR, and the game fills your view. Without a headset, any current browser on a phone or computer plays the same games.

2. Getting a game onto the headset

Type the address. Open the Browser from your apps on the headset, select the address bar and type bruna.world, then choose a game. Each game also has an address of its own: momijigo.bruna.world and god.bruna.world.

Send it from a computer or phone. Under the game on each game page of this site is a Send to Meta Quest button. It opens Meta's website in a new tab, which sends the page to the Meta Quest Browser on your headset; you need to be signed in there with the same Meta account as the headset. The games' own start cards offer the same as Launch on your Meta Quest device.

Keep a bookmark. Bookmark the game in the Meta Quest Browser and next time it is one press away.

3. Entering VR and AR, and leaving

Each game opens on a start card over its scene. In the Meta Quest Browser the card shows Enter VR where a computer would show the Send button. You can also go in later, from Enter VR on Momiji Go's main panel or God: My World's world panel.

On a headset with passthrough, such as Meta Quest 3, Enter AR appears beside it. The games offer it only when the browser says it can open an AR session; without it, play in VR. In AR you see your own room:

• Momiji Go hides the temple garden. The board, the bowls, the cushions, Lord Tsukikage and the panels stand in your room, the tatami level a little above your floor.
• God: My World puts away the god's study and the sky. The carved table and its world stand in your room.

To leave, press Exit VR on Momiji Go's main panel (Exit AR in AR), or Exit to Browser on God: My World's world panel. The game is as you left it. The headset's own way out always works too: press the Meta button on the right controller, or use the headset's hand gesture for its menu, and leave from there.

4. Hands or controllers

Both games work with Meta Quest controllers and with hand tracking. To change over, put the controllers down: if hand tracking is on in the headset's settings, your hands take their place when you hold them up in good light. On a panel, point at a button and pull the trigger, or pinch your thumb and index finger.

Momiji Go

The board answers only to touch, never to a ray. Touch a crossing with your fingertip, or with the tip of a controller. The stone goes down as you lift off, and a hand sliding across the board plays nothing. The Play key on the settings page chooses one of three ways:

• One tap: touch the crossing and lift off. The game starts with this one.
• Two taps: the first touch rings the crossing; touch the ring again within six seconds to place the stone.
• Grab and place: reach into your bowl, with a hand or a controller, and a stone comes away with it. Then touch the crossing.

If your first stone hasn't gone down after a while, a YOUR MOVE card rises over the board and shows a hand playing each way. The bowls can be picked up with the grip button or a pinch; anything dropped or thrown goes back to its place after fifteen seconds.

God: My World

Each power has a gesture. Your left hand points at the land to choose the place, and your right hand makes the gesture; with your hands, a pinch does what the trigger does. For Rain, pinch, pull back like a slingshot and let go. For Lightning, swing the hand down fast. For Fire, hold the trigger and spray.

Choose a power by pointing at its tile and pulling the trigger. A guide on your left then plays its gesture with two hands, until you have released that power once. To do without gestures, open Settings on the powers panel and press Release: Hand Gestures so that it reads Release: Point and Click: you then point at the land and pull the trigger for every power. To move, walk, or use the thumbsticks: the left one glides you along and the right one turns you. The God: My World guide explains each power.

5. Your room and your comfort

Inside the boundary your headset asks you to set, clear the floor of anything you could trip on, and leave room for your arms.

Momiji Go is played sitting down, on a chair, a sofa or a cushion on the floor, and it never moves you. During a session, open Settings on the main panel to find BOARD HEIGHT. Lower and Raise move the board and everything around it 5 cm at a time, from 20 cm below where it starts to 60 cm above. VR and AR each keep their own height; in AR, set it to a table or leave it low for the floor.

God: My World is made to be played standing, at a table just in front of where you start. Its world is about five metres long and three deep, more than most rooms hold, so take a few real steps and lean in, and use the thumbsticks for the rest. Gliding with a thumbstick unsettles some people; walking is gentler.

• Hand tracking and passthrough both work best in a well-lit room. Neither game has a brightness setting of its own; the headset's display settings apply.
• Take regular breaks, and stop if you feel unwell. Meta's health and safety guidance for your headset applies here too.
• Neither game has a clock. Lord Tsukikage waits for your move, and a game in progress lasts as long as the page stays open. God: My World saves your world every few seconds and when you take the headset off, and nothing happens in it while the game is closed.

6. What the browser may ask

The first time a page enters VR or AR, the Meta Quest Browser may ask whether to allow it. If you refused, Enter VR may then do nothing, because the browser remembers your answer for that site; change it in the browser's settings for the site, then reload the page.

Only God: My World asks for the microphone, and only when you press Mic in a room under Play Together. You never need it to play. In VR, the first press says: “The headset leaves VR to ask for the microphone. Press Mic again to go on.” Press it again, answer the browser's question, then press Back to VR at the bottom of the page. Once allowed, it is not asked for again, and VR is not left.

If it is refused, the room panel says what to do, such as “This site is blocked from the microphone. Allow it in the browser's settings for this site, then press Mic again.” If it says the page around the game does not let it use a microphone, press Open the game on its own on the game's page here. Momiji Go never asks: its two-player games have no voice and no chat.

7. Offline play and the home screen

Momiji Go keeps a copy of itself in your browser after a visit online. With no connection, open momijigo.bruna.world in the same browser and play Lord Tsukikage at any level, or the lessons. Two-player games still need a connection. To be ready:

• Open the game once at its own address while online. The pages of this site need a connection.
• On a headset, enter VR once while online. The models of your controllers and hands are downloaded the first time, and the browser keeps them.

On a phone, Momiji Go can be added to the home screen with the browser's Add to Home Screen option, and then opens without the address bar. On an iPhone, where a page can't go full screen, this gives the board the whole screen. God: My World keeps no offline copy and needs a connection to start, though your saved worlds stay in the browser.

8. On a phone or computer

Without a headset, both games play in full; only the controls change.

• Momiji Go: click or tap a crossing to play. On a computer, drag to look round and use the mouse wheel to zoom; Reset view on the settings page brings you back to the board. On a phone, the two panels fold into tabs at the top.
• God: My World: choose a power, then click or tap the land. On a computer, right-drag turns round the table, the wheel zooms and WASD moves. On a phone, drag one finger to go round the table and pinch to zoom.

Under the game on this site, Full screen gives it the whole screen, and Open the game on its own opens it at its own address. The full controls are on the Momiji Go and God: My World pages, and if you are new to Go, How to play Go covers the rules in five minutes.

9. When something goes wrong

Enter VR is missing

• You are not in the Meta Quest Browser. The games show Enter VR only when the browser says it can open a VR session.
• The link opened inside another app. A chat or social app may open links in a browser of its own, which may not offer VR. Open the address in the Meta Quest Browser.
• The page is not secure. WebXR works only on pages whose address starts with https://. Type the address yourself.
• The start card has gone. It leaves once you start playing; use Enter VR on the game's panel instead.

A black, frozen or endless loading screen

Both games need JavaScript turned on. On a slow connection Momiji Go says it is still on its way, and if the load fails it offers Try again. God: My World shows a moving bar; give it time, then reload. If the picture freezes or turns black in VR, leave with the Meta button, reload the page and enter again. A reload starts Momiji Go on a fresh game, though your finished games stay under Past games. God: My World comes back as it was last saved.

No sound

Browsers keep a page silent until you click, tap or press a key on it, so both games start their sound at your first press. If it stays silent, check for Music: On on Momiji Go's settings page, or Sound On under Settings in God: My World, then the volume of the headset or device.

Stutter or a low frame rate

Both games ask the headset for 72 frames a second. If they stutter, close other browser tabs, above all other 3D pages, since every open tab shares the headset's memory and processor, then reload the game. Restarting the browser or the headset clears anything left running.
