Hey there ladybug_games, I got your game for judging so here are some of my thoughts. Good use of custom art, and I love the idea of using paintbrushes to bring color back to the maps. Drifty has already shared a lot of the same issues I had with gameplay, so I'll try not to repeat it. White words on a white background made dialogue hard to read, I wish you had either made the message windows darker or switched the words to black instead.
I'm sure the deadline kept you from adding more items and enemy types, but if you keep working on this project I hope you add some more. An item where you throw paint instead of a rock could offer up some new ways to solve puzzles, and maybe a leech that doesn't attack but instead searches the map to remove color could force players to defeat it before they can focus on the color map.
Overall, congrats on making a interesting puzzle game! There are places that could use some more time and polish, but the puzzles themselves are fun and rewarding to solve.
