What if TRON was about acid music?
This game is a trip, a trip in an other-worldly place. Music is everywhere as you explore these lonely, neon-lighted landscapes, but music is made by the world itself. Weird geometric elements of the decor radiate short, acid-synth tunes. You will encounter puzzles where you build such small acid melodies to open passages. As you progress into the game, you unlock parts of "the studio", an in-game audio-sequencer where you can export the tracks you make (the game manual has 8 full pages dedicated to the studio).
On the gameplay side, the puzzles are pretty easy. They change the rhythm of exploration, which is good, but are a bit repetitive. That's why the whole game is more a trip than a puzzle.
In my personal taste, the music lacks bass and a bit of BPM, but it probably fits more with this calm world animated by music. For me, the trip was more a visually-stunning trip than a musical trip (I'm rather a visual person anyway), but I'm a TRON fan so I'm fine with it. I was just expecting a little more from this sound game but it's still pretty good.
My trip was sober, but perhaps the game could be even more interesting if played differently.
