Played the Wash commission on a phone (Galaxy S25, Chrome, touch). Laying water and pigment in a grid of dabs and watching it spread into one sheet, with the edges darkening on their own as it dried, was the moment it clicked: you really are timing the water, not drawing. On a phone screen the paper and toolbar are quite small, and after I hit deliver and let it dry I didn't spot the judging result anywhere, so I'm not sure if it's below the fold on narrow screens. Lovely idea for a sim jam.
