Pretty neat game but I wish there was a tutorial. Took me some time to figure out what I had to do. Initially I tried to catch all of the ingredients and I was very confused about the green splatters on the screen.
I found a few bugs. You can have up to 3 recipes you have to complete. When there are two or more recepies, I start collecting the ingredients for the first one and when I complete it, it dissappears. Then I start collecting the ingredients for the second recipe. While doing that, a new recipe appears in the first slot and now the items I collect for the second recipe start applying for the first one resulting in me getting the items wrong. And on top of all that, it is random as to when it decides which ingridients to which recipe to apply. The first ingridient is counted towards the second recipe. The second and third ingredients count towards the first recipe. However, the forth ingredient counts towards the second recipe.
Some times the recipes would not have icons. Not a big issue as the icon is not a part of the game play but it is a bug.
I would make the recepies be a queue: Initial - [Recipe 1, Recipe 2, Recipe 3, Recipe 4], then after completing Recipe 1 the queue becomes - [Recipe 2, Recipe 3, Recipe 4] and then when a new recipe appears - [[Recipe 2, Recipe 3, Recipe 4, Recipe 5]. Add a way to mark the first recipe in the UI and you will have a real neat game.
Try to add some obstacles as well which the player have to avoid as catching the would ruin the recipe and you would have to start over.
