Hello, dude! Its maybe my failure, but... I do not have any sounds or music in the game. And also I dont see any options and my game can be only in windows mode (I cant make it in fullscreen mode... Or even make the game in bigger screen...)
I dont know, may be its not errors and everything of it should be, but you have a link in the game to musicwriter (Or no...?), so, I guess, that its a real bug
Upd: Oh, wait, about the sounds was not a bug, its just me dummy :p
But anyway, the game does not have fullscreen mode...
