Thanks for the input both of you!
1. I do understand that I need som graphics. I hope I'll find a designer who would like to do some artwork since I suck at it. I actually thought the image I have now was a good alternative (many online browser games have a rather cartoonish design) but aparently I need to change this for something better looking
2. What do you mean with more information? Do you mean more game statistics and game information? As you've pointed out, the main focus hasn't been on the design, but I'd like to do everything I can to make it interesting to play.
3. I'm actually not that fond of lots of javascript effect. But I might rethink this if you think it would make it look hotter. My belief is that the page should be usable without javascript, but since the in-game map is made with ajax, one would probably need javascript anyway to play.
4. Interesting. Personally I think the colors look ok, but I've been working with it for some time so I've gotten used to it. What is it that you don't like? Is it the combination of colors, or do you think it makes the text hard to read?
Maybe I need some opinions from more people to come to a conclusion on this one.
I'm glad you like the idea and took some time to evaluate it. Your feedback is appriciated.
By the way, John, what was the error you encountered? Was it on the main page or in-game?
