After a year in Early Access, the music-making puzzle game Sentris is officially out today.

What's great about Sentris is how accessible it makes crafting your own melodies and beats. It's like a toy; you control bits of sound on a rotating disk, swapping them out as it turns and adjusting for things like tempo, key, and scale.

There are pattern-based puzzles to master across 20 levels, but also an endless mode that lets you fly through the game's psychedelic backdrops and synthesize sounds at your own pace. Because the song is always looping while you play, it's fun to watch and listen as new melodies emerge.

You can buy Sentris for PC, Mac, and Linux on Steam, the Humble Store, and itch.io.
