Fun game but VERY hard. I think switching between lanes would be a better mode of determining where you paint as it still is a timing game then. But moving the painter AND timing the keypresses correctly AND keeping track of which paints I need to switch between is too much for me :P
Aestetics are on point and the music is more chill than I feel when playing this game :D
I got closest on level 2 where the bulk of the work is in the big large lines:
Great job !
