The full 2-dimensional range of mouse-look allows the player to fine-tune the perspective-angle reflected by divisions designated by position in 3-dimensional space. It works very well.
I found myself enjoying the discovery of beautiful symmetries and then moving away from them with subtle mouse-movements to a new symmetry, trying to remember my path with visual cues, and then navigating back. It's quite beautiful and I enjoy how the visual space is navigable in what feels like an additional dimension.
There is a wide spectrum of colorful, planar sculptural forms worth witnessing here. The soundscapes suggest various physical textures and urgencies.
