I hate how if I have dartling guns and banana farms on the map at one time, I have to change the direction of the dartling gun spray to collect the bananas, which means the dartling gun will be less effective. Sadly, I have to buy the special building for the dartling guns and fully upgrade it if I want to put the dartling guns into a fixed position, which means I have to spend a lot of time saving up the monkey money and then spend it on the special building that has 3 advantages but only 1 that I actually need. I wish either we could automatically have the ability to put them in fixed position or we could decide which upgrade we want from the special building when we pay the monkey money. Of course, the upgrade that gives you free stuff or enhances the weapons power will cost more.
