You made a good alchemy game.
At first it wasn’t clear how everything worked, but after I understood it, it was fun to experiment.
I think your game mainly suffers from the problem of showing too little information to the player. (As are my games in general.)
It took me a while to figure out that you spend mandrakes to get feathers (a little animation might help). It also took me a while to figure out which buttons to press to collect things (write the command in the corner of the screen or do something like "LMB: collect"). Showing which side of the pentagon is responsible for which element also helps people experiment. And the feather has some strange center of mass.
And the screen shakes too much.
And even with this, I enjoyed playing. The scenes in particular didn't disappoint <3
I wonder what you'll do next time.
