Adorable little defense game. I felt like it was too easy though. Could use some higher difficulty settings.
A minor bug I encountered is that you can move buildings below the "choose new card" menu when picking a card.
The building/planning would be so much better if we could build ontop of torches. They have such a low radius, that they are inevitably everywhere, and block efficient placement of marketplaces/house and other setups. What if, when you placed a building ontop of a torch, it became a lantern on the roof (just for cute visuals)?
Also it would be nice if you could chop down trees with the sawmill - it's highly profitable, but could leave your base more exposed if you chop a lot of forests. Also it gives incentive to expand outwards to claim more forests to cut - and most importantly - gives more space to build, because towards the end, it gets REALLY cramped (the torches aren't helping there either.)
It could be an upgrade card - sawmills generate twice the gold, but chop down all adjacent trees each day.
