Nice models, textures and UI.
Looks really good, downloading now.
If I had to make a criticism, it would only be the text colour on the main UI for New Game; Options; Highscore; Exit; It's quite difficult to read.
Will post more when DL complete
Completed to wave 13, could of lasted longer, but work to do
Really nicely put together, great particle effects, models, camera movement, the whole thing looks well thought out and made professionally.
