Hey, brought you some words to read :D
Just played your game and found it oddly satisfying. idea is simple, end goal is clear, music is atmospheric. Sounds like a perfect ingredients for a great game :D
Creating potions make you feel your progression, therefore the game doesn't feel boring. but it might be a bit too overwhelming for a new player, i had a few brainlags during my playthrough :)
Main issue is UI not being intuitive. Would be cool to somehow separate "ingredients", "Result", "Workstation" icons in the potions book and sort it in different categories like "ingredients" and "Usable" (or something like it)
Also i found some bugs:
-Weed killer have wrong icons in recipe (or wrong description)
There is also 2 potions called Weed Killer.
-Sometimes when you pick up ingredient something like invisible wall spawns in front of you.
-Movement in the house is a bit weird
-Also it might be a good idea to let player walk away from "Use potion sequence" instead of gazing on timer, counting your last seconds:)
Overhaul the game feels great and deserve more ratings in my opinion :/
Good luck with future development!
