Hmm, thats a point. One of the rules said that game should be playable without sound, so I didn't pay attention to the processing of sound commands. Thanks, will try to implement something meaningful.
I have a problem in the TERMINAL location. It is not indicated how to go out, and I had to use "EXIT" but it is not indicated. In the smarlet there was "RETURN".
I also have the light, but in the terminal and the smartlet, I have to focus my vision.
