click the button that says T (for towers) and choose one of the boxes to show what you can buy, when you click the box hold down and release where you want to place the tower. Cannons are aimed by your mouse. Defend the pink area by shooting the rockets attacking!
I got the Idea of this from the app Bloons Tower Defense 5 And played around with it a bit. There will be updates to this game Update 2.0! now you can upgrade towers to work for you better then ever. there was also a bug fix in this and 100 times better music. Just to let you know upgrading 1 tower upgrades all of that type. Update 1.9! Now, every 30 seconds rockets will stop coming, dissapear and you have 10 seconds to place down towers. Also you now get slightly more money deafeting higher level rockets every brake you get 100$ update 1.8 green rockets have lives and you get less pay from destroying them and several bug fixes. update 1.7 orange rockets have lives shooting rockets is worth less Update 1.6 new canninball color. Gray to black update 1.5 Volume buttons acually work Update 1.4 Sound Track Update 1.3 Bug fixing. New Update!!!!!1.2 Infite places to put your towers! Thank school for being so boring I decided to think of a way to do this instead of paying attention. Update 1.1 more tower slots
