I loved the game, but as you said, it is still a prototype. It would be really cool if you added level ups to the buildings, maybe the lightning could level up some buildings that have a continuous effect like the barn.
I also noticed a bug that when you finish a level and press "continue" you will play a turn and then the same notification that you finish the level apears. You could make a infinite gameplay that the tax increases every X number of weeks.
A great addition would be a skill to move the buildings, similar to destroying, you earn "move" points with builds you every tax you pay.
I would love to see night maps or snow maps or anything like this, different biomes and such.
I think a nerf in the lightning would be great, having in mind that you can spam lightning and earn 900+ gold in one round. You could do that if you struck any build with a lightning, the next lightning in this build will make 10% less gold or something like that.
I noticed something frustrant in the game. I couldn't see what the building did because if I clicked on it, the card would appear off screen.
New buildings every level would be a great addition too!
All in all, the game is great, keep up the good work. Also, the art looks great.
