Play the riff. Own the stage.

Riffvolt is a four-lane rock rhythm game for the browser. Players hit notes in time, hold long notes, bend them with the whammy and fire up overdrive. 12 full tracks, four difficulties and a four-venue tour are already built in. You get a finished game, ready to upload and make your own.

Riffvolt: play the riff, own the stage. 12 tracks, 4 difficulties, 4 tour venues.

12 tracks, four charts each

Every track has Easy, Normal and Hard charts, plus Rock God, which opens once the tour is finished. That is 48 note charts in total, from Basement Static to the title track Riffvolt.

12 tracks, with four chart difficulties for every song.

From the garage to the arena

The tour runs through four venues: Garage, The road, Festival and Arena. Each has three songs; stars from the first two open the encore, and finishing the encore opens the next venue. Story scenes and cosmetic rewards, such as trails and frames, mark the way.

From the garage to the main stage: earn stars, unlock encores, follow the story.

Catch the note

Tap notes on four lanes, hold long notes to the end and bend them with the whammy while you hold. Timing accuracy builds your score and combo, and overdrive adds its own light show.

Catch the note: long notes, whammy and overdrive.

Your keys, your touch, your rhythm

Play with D, F, J and K by default, tap the lanes on a touch screen or plug in a gamepad. Key bindings and gamepad controls are in Settings. Free play opens any song at any difficulty, and personal records are saved song by song.

Your keys, your touch, your rhythm: keyboard, touch and gamepad.

Tune the experience

A built-in calibration sets the audio offset, which helps with Bluetooth headphones. Reduced motion and a photosensitive mode tone down flashes and lightning. The interface is in 14 languages.

Tune the experience: calibration, reduced motion and 14 interface languages.

A smooth start for your project

Upload the game folder to an HTTP(S) host and it runs: no PHP, no database, no account. The illustrated English and Portuguese manuals cover installation, controls, the file map, adding songs, local saves, dependencies and troubleshooting.

Do I need a server or database?

No. Upload the contents of the game/ folder to any static web host and open index.html over HTTP(S). Progress and personal records are saved in the player's browser.
