press space to make circle green flag to erase you can make many circles at once do NOT CHOOSE a number larger than 120 it is fine if you pick a number smaller than 30 but the circle will be very small you can select colours [when asked to select colour] but red, green or blue. I will add more colours in the future. also the project will ask the colour you want for every circle but you don't have to type the colour every time [you have to type again if you want to change the colour]. after you have picked the colour for your first circle and it asks the same question again, just click enter [or the tick button] and it will make the same colour circle again. this will not work for size [if you do the same thing the no.of circles will increase but it won't make much of a difference] also try out this project i made https://scratch.mit.edu/projects/1321247686
