Great tower defense game! Art was simple but everything felt sleek. Sound was pretty relaxing as well, I enjoyed the recourse management aspect of the idea akin to a Factorio x Balloons Tower Defense kinda game. If this was more polished it with more content it could be even better. Great demo for a great idea. The only feedback I might have would have been including the loop theme into the game a little more, as from what I gather it's tower defense game (which I guess is a loop in it's self of buying new stuff), and the towers were circles. Very well executed on a very well thought out idea. Love this!
