Feedback:
The platforming is very buggy. Flying up into the air occasinally, hanging on walls (I assume that wasn't intentional since it holds no utility), maybe some other stuff.
The theme seems to have very little to do with your game other than minor aesthetic choices such as some backgrounds and the music. The backstory seems completely irrelevant to the game itself, you may as well have said here's two people going on a break, here's a seperate 2d platformer. Picking up the portraits doesn't count since these may as well have been keys. The jumping around as a whole didn't seem to be explained anywhere (I didn't reach the end because I got bored - I've played enough 2d platformers in my life - so maybe it gets explained later).
The frustrating trial and error platforming also clashes quite a bit with the atmosphere.
The platforming (apart from the bugginess) was pretty good, I quite liked the backgrounds and the music was really nice so this isn't too bad, but no innovation or real theme fitting and clashing aesthetics and interaction.
