Going from 0.7.2 to 0.8 there's:
- A new item you get when exploring that makes it so you always start a battle with at least 5 energy
- If you go to the Dorstore while you have a mushroom and you can meet the Turtle Alchemist and he'll invite you to his lab at the pier
- You can give mushrooms to him to get access to 5 new potions and if you give him enough mushrooms you can eventually battle him
