Ah, that's weird : It is a game I wish I loved. But the puzzle are interresting, But I can feel that I am colonizing Mars. So I can stick to it.
And it might actually come from a very tiny thing : the fact that the 3 way repartiter creates 3 "crystals" sprite (which is my mind is local ore) instead of "energy" sprite (used crystals, turned into energy) breaks my immersion...
