The art is absolutely gorgeous!
I really liked the mechanic! Putting all four ingredients (even if the combustion "state" of the potion has already been reached) isn't the most intuitive in the world tho, but once I got it, it was really enjoyable!
The one thing I cannot forgive is the lack of an explosion. I was so looking forward to it given the amazing art 😭
I did like how you scale complexity with each level. Really had to stop on my tracks and think about what I was doing. Great job!
