Great game ! I'm really racking my brain trying to finish my first case—the ballerina one—but the last four steps are giving me a hard time. I've noticed a few bugs : the "cd .." command moves up two directories instead of one, and sometimes windows get "stuck" to the mouse cursor, making it impossible to close them. Also, the mouse wheel should work normally everywhere; in the command prompt, a single scroll up sends you all the way to the top.
