I really enjoyed the parallax effect and overall art style.
Sound effects are alright, but even at the lowest volume, some sounds were so loud that I almost went deaf.
The gameplay is cool and reminds of Undertale, but it doesn't require much thinking, just pure reaction. I would have enjoyed it more if, for example, I had to bait the painter to drop whatever he drops on the heart to progress.
Great entry overall. Complete and features an ending, too!
