Up and down key to toggle between drawing and not. Use mouse pointer to control. Not mobile friendly. There is no undo button cuz I don't know how to code it and I'm lazy. Hover your cursor over a colour to change to using that colour, same for everything else. Suggest colours in the comments. C to turn on eraser. V to turn it back off.
Thanks to @sunshadow49 for the music "Frozen Droplets"! blonk
