I really enjoyed this game mechanic. Art is nice but too minimal, I think. Sound effect are also nice too.
I just noticed that I spend most of my time painting every single object in the game.
I'm glad you liked it.
And yeah, I had to make some tradeoffs on the environments to finish on time. Most of my graphics time was used up by the player character animations. I felt the most important part was making sure the paint mechanic worked.
