The environment didn't display in the browser (if it weren't for your screenshots, I wouldn't have understood what it should look like in the game). I downloaded the installation file and finally got a feel for the whole idea. Great job!
Great idea. The loading screen is absolutely fantastic, everything is so beautifully designed. The only thing missing is some grass and trees, otherwise it's unclear where to go in the background (though maybe that was the intention). It's also unclear which buttons to use for attack, etc.
