Excellent little deck builder!! Very nice!!!
In case you are still updating the game (since it's a jam game) a little feedback. Show on hover over each planet card the total resources (or even better also a more detailed summary) acquired when you play this specific card. As it is now you only see the new global total of resources if you actually play the card.
Finally it is possible to put (even untested) a linux version of the game? Since you are using Unity game engine.
Thanks for the feedback and I'm glad you enjoyed it! We aren't planning to make any changes to this game as there are a number of things we would have done differently if we weren't limited on time. Instead we have decided it would be better to make a new game that is similar to this one, and we will try to incorporate all the great feedback we have been getting.
Also I uploaded a Linux version of the game for you. I'm not sure if it works or not so let me know if you give it a try.
