There are some good artpieces here, but most of them are, at best, mediocre.
My main issues:
1- You have to click in the artpieces to advance, and because not all of them have the same size, width and long, it becomes annoying sometimes because you're already used to click in a specific part. This makes the image go blue/grey for a moment until you get it back. It would be better if there were arrows.
2- Returning with the interface: It sucks. It's plain boring, a static black background with the images, a lot of people here have already participated in other collabs which have way better interfaces, for example the Art Gallery Collab which had a color background and a arrow, at least that would've been better.
3- Some artpieces don't have the signatures/names, so you don't know you made them. Using the Art Gallery Collab as an example, again: It also had the artist's name at the left.
4- There's no background music, making the game more plain and uninteresing.
