Nice and cozy game. Did enjoy finding these Imps in some of these art pieces. Three nice calming tunes helped as well. Finished up as well, but had to use Hints a few times. These imps were fairly well implanted onto the pics :D.
My most favorite imps to find were in those pieces:
1. Bateman
2. Ivan Bilibin
3. Haeckel
I personally didn't enjoy looking through them on the Van Goth and Arcimboldo pieces. Felt like there was a tad too much detail/colors to find them.
