Laid back and chill game, very cute
I did have a little trouble with the ingredients, like knowing how they'd affect the potion's quality. The labels on the left perfectly describe them, but trying to read them while hovering my mouse over the object broke my brain. Part of it might be the unfamiliar font (although the hand-drawn style is very chic), but I think the biggest issue was that there wasn't much wiggle room when highlighting an ingredient by mousing over it - the candy is particularly troublesome with the gaps in its sprite
I think it might be nice to have an idea what kind or how many ingredients you still have in stock, although that might detract from the mechanics of jumbling it up and shuffling. I did find I wished I could press a key to refresh my ingredients, although this was a rather personal issue: my cat is sleeping on my mouse and generally making it difficult to play games today :P
I had fun! I dig your style and sense of humour. Good game!
