Well, the title claims that it's the "Best 3D Engine," but not really. It's still pretty good, but Megazeux wasn't really meant for 3D. What would make it better, however, is if there were items, enemies, and different rooms. You have an automatic gun and you have to go around some walls. Other than that, well, that's it. Another thing, if there were some music and sound effets, the engine would be much better.
