Nice game!
I think potions requiring "ranges" like energy, toxicity, etc, is a really unique way to go about things.
The icons for the ingredients also look quite nice. However, I think the shop menu could do with slightly better formatting, as some of the icons and prices overlap each other. I also think it could have fit with the theme better if there were worse consequences for making the wrong kind of potion, as currently it seems things can go wrong without much consequence. Other than that, I think you have a really cool take on a potion-making game! great work
