Some pngs are 32bits despite perhaps not needing it, for example rock.png. Should that really have an alpha channel? Of the other textures, say the city detail textures, do you assume 1.0 alpha if no alpha channel?

Unity assumes one if no alpha is present I believe.

Yeah, they could definitely be optimized... on my todo list. working on incorporating dxt caching into ATM at the moment.
