this reminds me of atari 2600 and those early text-driven PC games. i like the story , despite most people's fear of darkness, it would be equally frightening if daytime stayed forever (which, IIRC is actually going to happen when the sun reaches its peak energy point , growing and consuming a couple planets including the Earth. your game has a touch of reality after all :)
i think, however, that exploration is the focal point of your game style. in the same way as "it came from outside" , there are only a few elements, so the player can fill the blanks with their own interpretations. in future games, you could exploit this cryptic nature even further for tension. Yume nikki immediately comes to mind. it'd be killer to play something like that with your "Blitsy" minimalist style, with bigger places and perhaps different types of interactions to make it work.
in all , keep the good job guys !! i hope you work more with this style and explore it as much as you can , you'll probably perfect it with time :)
