I loved the engine! Everything feels very dynamic and alive. But I think it's missing something. Well, to be honest, I think it's a shame that it's actually just a death match game :(
With the atmosphere you bring here and the greatly timed bullet time moments, I can imagine great games coming from this engine.
You're obviously a greatly talented programmer, but I honestly think that with the help of some talent in other areas, such as level design, sound design, character design and maybe a writer. This could become much more than what it is now.
Please don't get me wrong, it's great at what i does, i'm just saying it could do so much more :)
