Day 23. Quite addictive thanks also to the dramatic music. The blend of town building and tower defense works really well IMO. I'm just unsure how the Blacksmith works. Without upgrades it says +1 damage, but there's also a progress circle as if the upgrade to add +1 damage per 3 days was in action. And how does +1 damage for every 5 damage work? Does that mean every day it resets and then the shots get increasingly more damaging?
