It looks like it's at about Quake I standards in regards to quality of models, though less blocky.
The Android clone didn't feature many animations for the bricks and items, so I'm wondering if that is a limitation, or just laziness in game development?
Enemy AI and responsiveness was looking pretty sluggish. Not even up to par with Quake I AI it would appear.
So I dunno, if it is an easy to use interface, then I can see some uses for it, but if these games are examples of it's limitations, then I'd say there isn't too much use for it.
Not trying to be negative here, I'm ALL ABOUT getting new development engines ported over to all things Amiga and BeOS for that matter, but from what I am seeing, this engine is kind of lack luster, and I sincerely hope I am dead wrong.
