thank you so much for the feedback! adding a fix for restricting tower placement is definitely one of my big upcoming priorities, agree that they shouldnt be able to stack / be on the path / water / air etc. I went with click-and-drag, and single-placement tools just to keep everything to the mouse for now, but you make a good case for other options. Will keep in mind all of your criticisms for sure, and the nectar disappearing is interesting, haven't encountered that but I'll look into it, thank you!
