Simple, entertaining, and different
My review is similar to most others'; this game was fun and out of the ordinary, and now that I've beat it I even feel a little accomplished as opposed to many other games where I just feel as though I've wasted my time.
A few Pros:
1. Nice artwork selection, definitely good to expose people to some of the more famous works if they haven't already seen them
2. The music was nice and fitting for the subject matter as well
3. The riddles were simple but really require the viewer to observe the paintings and take in everything, which I personally feel gave me a greater appreciation for the works
4. Educational!
And some Cons:
-1: Pixellation! These are some of the most famous pieces of art in the world, and I feel as though there is something detracted from them when they have big blocky pixels strewn throughout. If you make a sequel, pleeeeease try and have as clear pictures as possible!
-2: Could use some more optional riddles, they were a nice touch
-3: There's not a sequel out!
I would love to see another game similar to this with perhaps a different era or style; Baroque would be nice, but maybe something more modern as well? I'd love to make something similar with your permission, or help create a sequel if you ever feel up to it. Nice work on everything though, and thanks for the awesome game.
