I enjoyed the fact that you found something other than “Another wizard/potion game” to fit with the jam themes. The shadow is also particularly useful when jumping around, even if you’re not in the air that long. Interactibles are well signposted.
A hang can be replicated in the second room by taking a photo of a Large object, then trying to get a photo of the other one. There’s no grace period for jumping when falling off edges, but the jumps aren’t so serious that it’s especially needed. Sound sliders could also be useful, though the game is short anyway.
