I also liked the game very much. Graphics and sound are excellent. At some points it is very hard to figure what to do, maybe next time make some clue mechanism. At a certain point, it took me maybe half an hour going back and forth to figure what to do next. This was BORING.
And please, don´t incur in space illiterate suggestions, like gravity being different in places with and without GRAVITY. This teaches people the wrong concepts. Maybe show magnetic boots being automatically turned ON when inside, that would fix it!
