The game has a great feel, it really is self-explanatory and it's beatifully designed. One thing I did see, though, is the layering once the turning sides(not tiles) came. That's it's little flaw, which I am sure the dev(s) won't make in future games. Nontheless, I enjoyed it very much. Well done.
Best regards, Paco :)
I love this game but it should really have the option to go fly out of mars' atmosphere. I had collected ~83k gold and was planning to land on mars when reached 100k but when i got at about 200k meters some magical force started pulling me (towards infinity maybe?!) and crashed me with immense force in an asteroid :D.
Lesson of this story: We'll never see Curiosity on Earth again.
