Decent, but slow, and having to search for the cubes is pretty dull.

As far as I got (until I couldn't find a required second cube in a level), every level is setup so you:
* Search for and take red cubes
* Place red cubes to reach additional cubes
* Use cubes to reach goal

No sound, no options, wishy washy mouse, unclear story/introcution (there is an intro, but I'm not sure why it is there, or why it used heavy motion blur), slow movement.
Sound design is decent, for the small number of sounds there are.
Small graphical glitches (geometry popping in when going around corners).
