Always a big fan of these "mix ingredients for a transformation" type games. I liked how you managed the hint system as a way to guide you towards the remaining undiscovered potions without forcing them to guess-and-check eternally.
The recipe book is a bit lacking, though. I'm not against writing down the recipes myself when I play one of these games, but the fact that not all the recipes can even fit on the page is really detrimental, although I presume that's probably a bug. I also like the descriptions of each item, as they can help figure out the effects of the reset items that can appear to do nothing if you don't have the property that they reset at the moment.
I also like the fact that you unlock new ingredients as you "harvest" them from some of the transformations. I would complain that some of these ingredients look pretty samey though. It's hard to differentiate between the milk, cum, drool, and love juice, and the gelatin too. The comparison is especially confusing between the Drool and Love Juice, and the Milk and Gelatin. Perhaps the Milk could be put in a bottle, and the Drool could be more translucent, or the Love Juice maybe styled into a heart-shaped puddle?
I assume this is probably due to the nature of the game being made from recycled assets, but a lot of the transformations seem samey or redundant. Like, the Salted Berry Syrup seems pretty redundant when the Goth Lemon Drops can just be combined with the Bacon Pancakes to achieve the same result.
