You made a nice twist on the "Grow a vine on all the matrix" type of game.
Not being able to have 2 vines of the same color next to each other plus the watchers going both up and down depending on the color was a real head scratcher. The game is also super clean and the color palette really pretty.
I do wish the game was more complete. Playing the game in complete silent and with a lack of a "congratulations" at the end was a bit of a bummer.
Nonetheless, the puzzle mechanics were fun and would like to see it expanded further.
Nice work !
