This is the best game I've played in this jam yet!!!! A tinyyy bit unbalanced, as dodging enemy attacks at first is hard to get used to, but when you get two archers, no stopping me anymore!
Couple of comments: add unlimited number of archers, but then increasing enemy difficulty as well. When i reached 4 archers, literally stood aside, had so much money with nothing to do with it.
Also, had trouble keeping track of my HP, the house HP, moving between buy menu and my hp, etc. It would be better if my HP was in the corner, and house HP was in another corner, both in the form of bars and not numbers. Easier to spot visually whether i need a heal or repair.
Also, it starts off too hard! Give the player time to get an archer, make it easier to dodge enemies, and then progressively harder. In the end when I mastered dodging attacks, no one could touch me. Maybe a ranged goblin? Same projectile and ai as archers. That would make things harder, giving the projectile some height to allow for dodging.
I really really really liked this game. What engine did you use? Pure SDL2?
