great little game, enjoyed the demo. But game is not at all intuitive, in the beginning you're not sure what to do and after about the 2nd or 3rd playthrough I kind of figured out what to do.
Also resource collection is confusing because I would click on the Fe and wood and they would fly away towards the top left of the screen, but the gauges there would not change, later I realized that the gauges for those are at the top right, maybe make the resource icons fly towards their respective gauges?
I know this is a first prototype, and I had fun with it, all the best with the development, I can see this being a great game :)
