About This Game

OTO is a music toy. Pick a world, start poking at it, and it makes music with you.

Tap the water and it ripples out in notes. Stack stones and the tide plays them. Paint the night sky and it sings back. There are twelve worlds in all, and I'll let you find the rest.

You don't need to know anything about music. The notes stay in key, so it's hard to play a wrong one.

Some worlds are calm and some are loud. One is a guided breathing session. A couple will play your own music.

Plays how you want

Made for Steam Deck. Works with a controller, mouse or touchscreen.

Colorblind modes, reduced motion, high contrast, flash limiting and UI scaling are all in the settings.

Who made this
I'm Hailen Jackson, an electronic musician. My music has been played on BBC Radio 1, featured on Bandcamp Daily and NME, and picked for Spotify's Ambiente playlist, and it's ended up in games and short films along the way.

OTO is the instrument I always wanted to hand people: one where you can't really play a wrong note. I made all of it myself, the music, the sounds, the code and the visuals. I hope you find a world you like!
