Cool idea. I like the two types of cards, which gives a cool bit of variation. Also, the cards gives it a good bit of randomness, though it also seems to be a weakness in this game (at least for me). I was often stuck just discarding card after card, trying to find something to bump up energy and not finding it. I also often seemed to get the same card a couple of draws in a row (very often the interstellar loan), which got a bit frustrating.
I also couldn't really find a good end goal to aim for. It seems like it's a "try to keep the colony alive for as long as possible" sort of game, but it felt to me like it needed some kind of goal or end point maybe.
