I really loved the artstyle and the SFX were really satisfying.
The enemies becoming vibrant and colored after being hit with the brush and the character doing the same thing when hit was a nice touch.
The music really gave Ari's determination to save her paintings.
However had a tough time differentiating the enemies on the second level from the floor tiles. They would confuse themselfs when grayed out. Also, the light green tiles are not always walkable and that confused, the paths weren't much clear.
And the frogs were a bit unfair because they didn't get knocked back and would always hit atleast once and if I was already low in health, I would have redone the level.
Overall loved the game, nice message at the end and it quite goes with the theme as those are really strange places.
