Being able to create this kind of game in such a short time is not easy, but you were able to do it. And for that, I salute you. The game needs a lot of improvement though, and maybe I can help you point that out. First, you need to add more information on what each buildings will do, maybe a context menu on hover. Next, you need to create a tutorial level. I found myself just dropping buildings without knowing what i really am doing. Which brings me to my next point, having only one requirement to build a building(i.e. wood) makes the game so easy. Maybe add more requirements like stone. Also add warnings or indicator for food outage, I lost the game because I had no idea my people are starving XD. Anyway, theres a lot of potential for this game if developed properly. Good job and good luck!
