Very fun! Didnt realize I could click on mountains to buy them. Also if you buy a unit and dont want to place it, is the idea that you have to? The pack is a random chance to see the options but I didnt see a way to reroll (buy new pack w/o choosing a unit). Hit a bug after 3 of choosing a unit, not placing it, and then trying to buy a third but the UI was open and I couldnt click it... I could buy more tiles by clicking on the mountains however.
