This was awesome! The music, the look, and the sound effects really stood out! I especially loved the beeping sound effect. Got a smile from me when it started. I think the only thing I ran into was the first command line prompt. After exploring for a while, I had forgotten that you could type hint to get information on the commands and pretty much sat there watching the timer go down trying to figure out what to input. Perhaps a text response on typing help if an invalid command is used would alleviate forgetful/not paying attention players from getting stuck?
Otherwise this is an awesome game! 10/10 from me
