It was a fun little game, enjoyable which is really all you could ask for in a game made in such little time. Aside from the obvious things like the text, the game felt a little too easy, with only one enemy type and one fighter, and of the five towers, the town hall seems useless and the fixer isn't clear on how it works, but if I understand it correctly is not necessary as very little damage was done in my play through.
I can empathize with being busy, We were too to some extend, and being alone as well makes it an even greater accomplishment to have finished a playable game at all. If you want to update it, I would personally add a couple more enemies and at least an extra defensive tower, along with a use for the town hall, or maybe I just didn't get it?
Anyway, props on finishing the game.
