Saw your pm and replied to that now =) In summary could be made more intuitive on some ends but there's something interesting there and the pushy getting beating sound when one builds something is cool, too =)
Regarding the engine: I see, cool =) Yeah, i'm usually less often doing engines on such closer to the metal ways these days, more often using more all in one packages like unity and pushing those with stuff they are not meant for =), so, nice to see other setups =)
Are you intending to release the game on more platforms? If so what's the porting path then?
