Ode, a new game from Ubisoft’s Reflections studio, is now available on PC. It’s described as a “journey of pure joy” — you play as a character named Joy, actually — that combines experimentation in open-world environments with musical puzzles.

If you hadn’t heard of Ode until today there’s a good reason for that; Ubisoft announced the game the same day it released it. Ode is from Ubisoft Reflections, the studio that developed Grow Home, its sequel Grow Up and Atomega, a stylish, blocky shooter with a growth mechanic.

You can watch the debut trailer for Ode above. Here’s the game’s official description:

Embark on a journey of pure joy, where every interaction with the environment has an immediate positive visual & aural reaction. Transform your character as you collect fallen stars and ascend through 4 fantasy worlds, revealing melodic landscapes to which you add layer upon layer of music to create a crescendo of sound and light.

Ode is available on Windows PC via Ubisoft’s Uplay service. It costs $4.99.
