Thank you for your comment!
Yes, now that I think about it, it's disappointing. Right now the algorithm behind the selling sysmtem uses the complexity (how many ingresients were used to make the potion) of the potion to calculate the coin amount that you'll gain. My idea was that implement a 'strength' variable to the ingredients and then feed the complexity*overall-strength to the algorithm, then it'd yield much higher selling value.
I hope that the game loop was enjoyable. 🙂
Again, thank you for your feedback!
