I like the game but the tower selection process is awful

This is a simple fun little game but every time I try to do something quickly you see the games flaws. It uses a tap when it should be a drag which is kind of annoying but it sets up the big problem. If you try to put a tower down in an area that isnt allowed every tower becomes blocked by text for several (exactly what you want when your rushed into an error). Every time it happens I want to throw my phone
