Simple and readable - like the Alchemist old advisor type. No idea what the PC was :D
GAMEPLAY
The core concept is great execution was good - would have liked to see some of the interactions challenged more rather than just the one interaction (which is probably a good sign). The player controller felt very floaty, but that's just normal gravity for you - next time try -30 or -40 as a start.
The aim of the throw frustrated me a couple of times trying to hit the pumice in the water in the bottom right - needed to go back and forth a few times ("don't need more than 1 - I will hit ti this time! :)).
I do wonder if you made the throw mouse based what options that would unlock with platforming challenges?
Bounce pads were fun!
Unsure on the use of the chests and candles.
UI
Nice, really clean - would have liked mouse scroll to swap potions.
OVERALL
Great submission, good idea - Well done on submitting!
