Auditorium is a very neat little...meditation tool? I hesitate to call it a puzzle game because the whole way through a level in Auditorium is nothing but zen and relaxation. When I think puzzle game I think mental stress; this is the exact opposite.
Each chapter is a song which is further broken down into levels of parts for that song. For example, the first level may be the bass line while the second and third levels establish the intertwining melodies. To complete a level all you have to do is direct the flowing particles to a certain destination. While there are some serious shenanigans that must be pulled to complete later levels, the atmosphere and music combined with the peacefully flowing particles creates this meditative trance that entirely drains away all of your stress.
On a side note, this game runs ABYSMALLY. On my overclocked GTX 680 I can only average 20-30 fps. Take one look at a screenshot and you will be baffled as well at such a terrible framerate. That being said, due to the minimalist design, a poor framerate doesn’t destroy the incredible feeling from playing.
Auditorium is a really cool experience, there’s not a ton of content but for a quick relaxing session it really is worth every penny.
