Excellent entry! The rootwarden moves so nicely and I love the satisfaction of placing a miner and watching number go up. At some point the walls became useless and I just started placing turrets everywhere. I never saw the boss spawn but that number went up too. For some reason the turrets liked shooting a rock in the top left of the map (maybe an enemy was stuck). I had a lot of fun with this and I think there's a lot of potential to build it out. Nice work!
