This is a pretty original idea and it might be worth expanding it for a bigger release.  I also like the story element.  It's actually really refreshing to see something that almost belongs to its own genre, and not something I see every day!  I think there is a lot of promise here beyond this prototype... maybe place it in some space station and offer the player alien artifacts!

This is a fun idea 

I was sometimes cut off by the end of the day

It reminds me of scp style games

Fun concept
