I'm not clear on how this relates to the theme? Quite polished (except for the extreme wall friction, which I found very irritating, and some occasional places where the colliders didn't match the art very well). Obviously a lot of work went into the art.
But this is more of a game design jam than a game polish jam, and I felt like the design wasn't that great.
The levels were too big: I forced myself to play through the theater level but they got tedious well before that. For me it wasn't enough payoff for all the fiddly little time it took to get all the collectibles. The art had lots of little corners and stuff to catch on. Having much lower friction would have helped, but if you want pictures this large and fiddly I think you'd need to tweak the controls in some way to make it easier to navigate small twisty spaces.
And it might help to make the darkness at least slightly different in color than the black of the levels? In one level I got stuck for a while because I couldn't see what was left to uncover (I had cleared it nearly inline with an edge in the drawing so it was hard to see).
But as a reflective experience just to chill and kill time I could see it working well. It's just a little too slow and with not enough to do if your goal is to see what the picture is.
