what? what do you mean by sword demon? what exactly happened?
oh I see. the tileset isn't loading for you? ok I'm going to need some details about the machine your running it on as well as the browser your using. also are you able to still move around and interact with entity's like the sign, or does the game just freeze? if it does freeze I'm going to need you send me screen shots of your browsers console. you can access it by going to the games page, having the game load, then hit f12 and go to the console tab.
