Thank you for these words! They mean a lot, really! Yes, we totally agree with you: as we were working on the idea, we noticed the points of connection with Superliminal, even though one of our favourite examples of perspective puzzles we had in mind is Tale of Scale, by Rat King (it should be still available on Kongregate if you want to try it)!
Also, yes we would like to keep existing art, ideally using some of those old and very complex compositions full of figures, objects, etc.
The idea of mixing the story of paintings and works of art with the story of Dr. Trompaloglio is great, thank you again for everything <3
