I made a little drawing game to test the pen tool. You get the smoothest lines when the crosshair sensitivity is set to 1 but drawing will be a bit slow, making the crosshair sensitivity very high causes weird grid stuff, I can't control that though that's a limitation with Scratch. The minimum size for your pen size is 63 and I can't change that without heavy modification to the game and it would be kinda jank, you're welcome to remix this though lol.
Controls: Q - Close/Open the settings sidebar. E - Hold this to draw. Arrow keys - Use this to move your drawing cursor. Space - Use this to change the type of shape your drawing. Erase all button - Use the button to erase your drawing.
