So creative and impressive! The mechanics fit perfectly with the theme and message. I'm so impressed with how well everything works. Love the freedom in where you can place towers, the slow unlock of new towers as you progress, and the useful mouse-over tooltips explaining the towers. My only minor gripe was that clicking the trash took too much precision, their small size in combination with the custom mouse cursor made it sometimes take multiple clicks to collect. Minor issue aside this is an awesome submission. Amazing job!
