Solid tower defense game, super easy to understand but not too easy to beat! I was confused on some of the mechanics though: On the later days I was able to start repairing one tower, but then wasn't able to leave that tower to start repairing another; I'm not sure if this was a pathfinding issue, or something else. I also don't think I ever saw a lightning tower do anything, but maybe I was using it wrong or just didn't notice. I'm not sure what damages my towers and therefore if there's any way to prevent that (they were walled off so no one should've been able to physically reach them, so it must have been ranged damage somehow). Lastly, is there a way to rotate walls/spikes before you place them?
I like the way that you have to balance the 3 tasks that you have - building, repairing, and attacking, and how the shorter and shorter nights force you to do this under increasing pressure. Spend too long trying to position that wall just right, and you've forgotten to move your servant to another tower needing repairs, or the night ends and you haven't built any more defenses! Great entry, I had fun playing!
