It's pretty cool and the music gives that extra bump for fun. But at some point my controls got reversed - not sure what I did to cause that. And the enemies seemed to only run away from me and got stuck in a corner until I shot them out.
I've done a "fake" 3D game like EOB before but this time I wanted to do an actual 3D game. In the end I realized that the benefits are less than the new complications that a real 3D dungeon crawler brings to the table. Should have sticked with the fake 3D.
