BROWSER BUILD // RUN-01
Delta-V is a free gravity-flight game that runs right here in the page — no download, no account, no install. You fly a small ship under an honest gravity model: hold thrust, let the planets pull, and try to arrive with fuel still in the tank. This is the same build that ships on Android, campaign and all; the difference is that the browser keeps your save in this browser, where clearing site data ends it.

Booting flight computer
First run pulls about two megabytes of engine and assets. It is cached after that.
LOCAL SAVE Progress here is written to this browser. Clearing site data ends it, and installing the Android app does not import it.
Hold the thrust control to burn. The engine is the only thing aboard that costs you anything — every second of it comes out of a tank that does not refill on its own. Short, aimed burns beat long panicked ones. Shift, or the boost pad, gives you more push per second and empties the tank faster.
Steering rotates the hull; it does not move it. Point where you want the burn to go, then commit. Nothing decelerates when you let go — you keep the velocity you built, and whatever body you are nearest keeps pulling. Falling toward a planet and burning across its face is usually cheaper than fighting it head-on.
The tank is the level. Canisters on the route top it up, and a leak will bleed it the entire flight, but the arithmetic never changes: you need enough left to stop at the far end. Arriving fast with an empty tank is the same as not arriving.
Both on-screen pads can be dragged to wherever your thumbs actually are, and resized from the HUD layout editor. The game remembers the positions.
Yes. The browser build of Delta-V is free, with no account, no payment and no download. The Android version is also free to install from Google Play.
No. The browser build is the same build the Android app ships — the full campaign, the garage and the salvage runs, with nothing locked behind the install. What the browser cannot do is guarantee the save survives a cleared cache, and the opt-in rewarded ads and workshop purchases need the native Android layer.
No. Delta-V runs in any modern browser — the page loads the engine and starts the game, with no plugin, no launcher and no sign-in. It renders through WebGL where the browser allows it and falls back to canvas where it does not.
Not by itself. The browser build writes its save to that browser's storage and the Android build writes to the device, so installing the app does not import anything and clearing site data erases the browser save. Delta-V does offer an optional Google account link for a cloud save, which is the only path that moves progress between them.
On touch, hold the thrust control to burn and use the steering control to rotate; both pads can be dragged to reposition and resized in the HUD layout editor. On a keyboard, W or the up arrow thrusts, A and D or the left and right arrows rotate, and Shift boosts.
Usually. The browser build registers a service worker and caches itself after the first load, so it will normally start without a connection — but a browser can evict that cache at any time. The Android build is the one that is always available offline.
