This one looked fun, but as you mentioned it was riddled with bugs. A big one is that if you brew incorrect ingredients, check the recipes with ingredients in the brewing ui, or close the craft menu with ingredients in the brewing ui, you are locked out of brewing (unable to craft any potions).
First time resulted in crashing due to clicking the brew button to many times with correct ingredients while brew locked. Second run I just did it with no potions, though at one point I somehow lost the potions display in the top-right. Third was my retry after reading your page and learning that help (?) is a main causer of bugs.
Though I wished potion throws spawned a little lower as being at the very top of the map throwing down would hit the tree hitbox. And it would have felt a lil better if the main character didn't default to facing me when I exit out of a direction. But, it was fun for what you have! I hope you can build and improve on it! Cheers!
