Nice little game. I liked the amount of resources you could gather, but also it was pretty confusion what to do. My bigggest problem was that I didn't understand the resources in the top left of the screen. I always tried to build the building that matched the resource that was labeled with a minus, but eventually I died - suddenly..? by building houses. CO2 problem here?
Yeah, so I think the most important thing to work on would be to tell the player more clearly whats going on: What to start with, what do the numbers mean. Oh, and when I tried to switch buildings, the map also zoomed in and out. This would be good to fix :-) Good job though considering the given time for the jam!
