Very intriguing game, I enjoyed playing it very much (even though my crappy computer can barely run it).
The story so far reminds me a lot of the book "Solaris" - any connection?
I would absolutely recommend it, it's a science-fiction classic (Link). Though be warned that Stanislaw Lem is not light reading.
My computer is an 8 year old notebook with a Geforce GT 745M graphics chip - that's really low-spec, so I doubt you can really do much about it on your end. I managed to get the game running with a decent fps, so it's not too bad :)
