I liked the concept of this! :) I'm not sure about the move/timer thing, since it didn't really hurt you to change maps, I never really felt the need for making a trade there. But other than that, I enjoyed it! :)
I am glad you liked concept of this game, thank you for you feedback :)!
(If you are close to gold, or you are on the gold and you don't have enough energy, there is a reason to make a trade.)
