I think there is a bug with the stew on level 1... When I get the scroll I can't read it from my inventory and when I talk to Lanugo he keeps telling me "It's all written down on this..." and claims to give it to be over and over and it never actually appeared in his bartering menu. A scroll does appear in my inventory you can't read it and when you use it it just says can't make recepie. He tells you what you need for it but nothing about a green mushroom so I presume you should be able to read that scroll. Not sure if anyone else had this problem also.
BTW awesome remake. I'm happy this exists.

Ah, yes, there are a couple of bugs there - he should say "just like the recipe I gave tha" not "tis all writ down on this"; and if you look at the scroll it should tell you the ingredients. Will see what's going wrong with the first and fix the second. Thanks!
[EDIT] I'll have fixes for these later today.
