I like this game, however, I think it is messed up there is no confirmation before spending diamonds. I was quitting a level earlier and a prompt popped up quick, which isnt normally there, right where someone would quickly tap though, after I tapped I noticed I spent almost all my diamonds on a power up, by accident. I don't waste diamonds on such expensive power ups. It may seem petty, but if devs don't want to do something, I will not be spending anymore money here.
