I tried it on a computer, it is awesome!, but if it is slow on a 3ds, and you want some type of dynamic background, just create a separate Canvas behind the other one, since Canvases are transparent :)
Of course you can! The 3ds Browser supports allot of fonts, check out

for some of the fonts the 3ds browser probably supports.
I normally use Arial and Courier, since they are supported on most Web Browsers.
How cares if it doesn't have a background image, or whatever, it is very well made considering it was entirely written by hand and the chat room looks great!
Guys! 3DS craft would be easy. You can easily play Minecraft on less than 1gb of ram on a computer. And if the game would be fully optimized, it actually would like lag less than a computer. It should be a downloadable game. P.S. They would make the game without Java.
