Well I tried the demo and the models look nice, Blackjack seems to work nicely, the water shader looks nice but the rest of the level really lets it down. Didn't really have time ( 6 mins is REALLY short ) but as far as I could see I think it'd be a good idea to replace the sprite trees with some proper trees. Mind you this kind of game seems all rather foolish to me so I'm not really the best critic.
