Click the water and buy upgrades. There is a weird glitch where you have to have one more water than the per second shop item to buy it. ¯\_(ツ)_/¯
@Gatsey for the shop items (sry i updated the shop skins and background because i did not like the scrolling one(because I'm bad at art) NOTE: l did not make the water icon (again because I'm bad at art) but l forgot to credit the person and now I can't find the scratcher anymore :.(
