It's good! The graphics are very pleasant and perfectly melancholy. Goes perfect with the music and the overall tone of the game.
Gameplay wise it feels unfair and is very unrewarding with earning money. Now that is of course the point of the game and is the most realistic way to go but it doesn't make for the funnest game and, despite my enjoyment of the dialogue, the visuals, and the music, I can't help but lose interest in the game as my hand starts to hurt from fruitlessly mashing the space bar.
That being said, it's a good game and I very much enjoy watching the paintings being made. I definitely am going to keep playing it even if it isn't the most rewarding experience which is exactly how it feels being an artist sometimes.
As an art piece I give this 5 stars. As a game I have to take off a star for the reasons above.
