While I enjoy the concept, I was a little disappointed with this game. The art and puns are great and I enjoy the "crafting" games (e.g. Potion Craft) but I got a little less puzzle from this game than I was initially expecting. I thought the runes that were used in place of the ingredients were based off of a font or something and that I could actually decipher them and learn them over time. I overhyped myself on the concept and ended up feeling that the puzzles seemed a little brute force-y instead. I do think the game is a good concept, but I also think that this could improve it puzzliness and make solving the pages a bit more satisfying.
Another thing that I wanted to mention was that because I was hyping myself on this idea, I put myself in a position where I wanted to get to the puzzle faster. The amount of text before actually getting to touch anything on the in game screen made me want to skip it faster. It wouldn't be respectful of me to leave that there without offering some sort of suggestion. So, I'd suggest making that conversation automatic. It can be happening but the player is free to poke and prod at the interactive bits as they see fit.
