A cool music puzzle game, with fantastic visuals! I appreciate the fact that there isn't penalties for playing wrong notes. It let the player experiment, familiarize themself with the sounds... And in the end, make complex patterns easy to remember! That's a clever game-design.
Just a detail: the message next to the first totem is easy to miss. That's what I did at least, and I had to wander for a bit before seeing it appearing, and understanding that I had to press E!
Other than that, it was a really great game!
