Half good
The graphics were stunning, and great soundtracks. The concept was good, but, as many others say, this needs a lot of improvement.
Its a lot of repetitive (the mined field and the walls part got to the point of being really annoying).
That being said, the annoyance gets deeper when it comes to the 3d sensation, even tough you added some red line to guide us on the ground, it can be really confusing.
Another thing was the points system, if you cannot perceive 3d too well, then getting enough points is almost impossible.
(the preloader music was very annoying too.....)
If those things could be corrected, this game would shine.
