Amazing, i can't wait to see how this game will develop, the settings are amazing, the idea behind it is really damn well made. I'll be following you from today forth Gentle Troll :D
Since it's in alpha stage, I hope that we may get the opportunity to experiment with the drinks, for example creating a good drink by mistake (as in an actual drink and then adding it to the book) or even a wrong one which may influence the adventurers in any way. Hell I'd even add a personality change while under the influence of the magic potions ,which can bring comic interactions or even results in quests, for an instance how in the tutorial when the bartender talked with Fable to add some "spice" in her life, why not add something that can influence their behaviour. This is just an idea, hope the development will be a success! had a lot of fun and I am considering buying the game once it comes out!
Keep at it Gentle Troll!
