Really creative idea, I also thought the art worked really well and the paint brush effect on the main character was a very good idle animation. I got stuck pretty early on so there might be more stuff that I missed but from what I saw the gameplay was pretty simplistic with not too much to do and I am also not quite sure how the game was related to the theme, but that could also have been something that was explored later on.
Overall really creative with an emphasis on art, well done! :)
