I would have suggested changing the link to the project site [1] instead of the download page since it has some sort of presentation that sort of details what it is about better, though it seems to be laggy or somewhat unresponsive--even though its transitions are very smooth.
The main page has shaders in background. This works well if your machine is beefy enough. But it's apparently an issue with systems such as iPads. I've temporarily removed the shader backgrounds.
It is totally broken now on chrome (desktop)
Their website doesn't work for me at all. It's just a blank purple with various navigation links that don't seem to do anything.
The 3D engine behind this looks very flexible while being easy to use which is pretty hard to do.
The programming language looks very interesting, especially the if declaration. It seems like a macro/runtime hybrid. Is it based on another language?
