It does not require any skill. This was made the night it was posted. Also enjoy the flag animations. You have to double click to get it to work. It goes an letter order.
This is runned off of my cell clicker. I copied it deleted tones of stuff then added new stuff. The towers code infrastructure is runned off of the same code design but changed numbers and such. please note that there is a flag. Natos flag to be exact. I definitely did not add flag animation but yea.
