It's super annoying when you try to click on a different tower but you already selected one and it just buy the tower you previously selected :(That's a good game I played it multiple times trying to loose 0 hp
Oh, I didn't realize that the turret instantiates to the last selected tile :P thanks for the bug report.
You can right click to deselect the current turret though :)
Yeah I noticed :) That was only on mistake
