I can't comment on the pricing, but IMHO both the description and the support website have room for improvement. Half of the short description I see in iTunes describes what the app can't do (no multiplayer over Internet). Only when I click on "more", I see the wealth of features. You could write "play with your friends on a local Wifi" and move the disclaimer to the extended description. Put a feature on top instead, like "robot players are pretty good". On the website, there is a lot of text, which is good because it shows you care. But make sure the features don't get lost in the details. Make them stand out and list the most exciting feature first. Strong robots and easy multiplayer game setup are probably more interesting than a Default.png graphic. Mentioning Default.png will only confuse them anyway, unless most of your potential customers are iPhone developers. Also, put the iTunes Store links on the bottom as well, so your visitor does not have to scroll all the way back up. Just my 2c, I hope you find some of it useful.
