Click and drag your mouse to draw a shape. The variable in the corner is how many sides the shape will have. Keys: W- increase the number of sides by 1 S- decrease the number of sides by 1 Space- input how many sides you want your shape to have Z- erase the most recently drawn shape A- animate your drawing (really cool) I am the test account of @scratch4tue Having made the square drawing project in that account, here I tried making an engine for all polygons. Sadly, it doesn't have the fill feature. Oh, well...
