Nice concept, I appreciate that a whole story was written to explain the gameplay, it's a nice touch especially for a jam game. As other people have said it's a bit hard to tell what is foreground and interactable versus what is in the background. The characters also felt slow to control and I think slowing down the player by that much when pushing boxes was unnecessary. The collider for the player also felt a bit too large, so when it looks like you should be able to fall through a gap you actually just walk over. These are all pretty minor things, overall well done!
