So I played your game and it's pretty nice, but I have some suggestions :
- the physics where you grab the ingredients with the mouse is nice, but it's a bit hard, most of the physics work but sometimes the ladle get stuck in the cauldron, for those who has this problem I recomend to use an ingredient to push it out. Also I starte by using my touchpad and it was a bit hard.
- fur/haire is a bit hard to grab because for all the ingredients you need to catch the actual drawing so you need to have the mouse exactly on one of the haire, also the fact they are tiny and black make it hard to see on the table. So maybe make his "hit box" larger or give it a slight glow?
- the recipe book is not really usefull, all it does is tell you the name of the potions you already made, which doesn't (directly) tell you their effects or what ingredients you need. Maybe add something similar to "tina's magic book" where you have a small icon and when you click on it, it open a window with all the recipies you have done with their ingredients and effects?
- in the description you should warn people about the futas tf, I'm personnally sucker for futas tf (hu hu humor) but I know than other peoples can be disturbed by this.
their that's everything I could see, you did a really good job, the drawings are nice, not a lot of bugs and the feature where Aethra tell us what flavor is lacking is fun, you find yourself exeperimenting with all sorts of ingredients to see which ones works.
I wish you good luck for your future projects ^^
