This was so fun! The characters were all super cool, and I loved their personalities. And all of the endings were super cool!
Includes spoilers: (but if somebody forgot to save before doing any of the extra endings or happening upon Ava, it does just kick you out to the title screen and remove all your progress. And it's not a game where losing progress will destroy you, but that formula puzzle destroyed me)
I wish I could say it was fun, but there's a few problems with it I'd say.
One, as mentioned in other comments, the satisfaction drops way too quickly. Between the time I can dump my balls and get another bunch of big balls, the satisfaction's already shrank to zero.
As well, what to actually do was unclear. Collecting the balls was self-evident, but knowing what to do with them was very unclear. It wasn't until one of the balls glitched and flew out of my cauldron into the dump-zone that I realised what the gameplay was.
And finally, some pre-warning of where the balls are dropping might be good, like a little light indicator a second before where from the top the ball will drop. It was always super annoying to see a ball falling on the very edge of the map, and not even having a chance to get to it.
I like the stubby, jerky movement of the cauldron character, it makes them feel more like a living entity rather than a gameplay thing. But the ball-dropping mechanic needs to be changed to make it actually enjoyable.
