Hey, I liked the idea. I always enjoy some balancing and stacking games. The art is clean and the UI looks great. I do have to mention that the UI does tend to get crowded or go off screen for me. For example Play and quit were overlapping and it was hard to click them. Also, I couldn't find the main menu button to restart the game until I full screened. Overall though I would say great job. I liked the little popups sliding out to guide me on how I should build.
