(Jam version)
Might have to split this review a bit:

As a clicker:
It's pretty click-heavy. Very click-heavy. It takes you quite a while to earn some automation, but it doesn't even come close to the power of your actual clicks, at least as far as I've seen.
There's not a whole lot of explanation with things, I really wish the game would give me a tally somewhere showing how much food is prepared, how many spare fishes I have, etc., and there's not much of an indicator if you're cutting/prepping too much/little.
Speaking of clicking, instead of the usual thing in clicker games where you can kinda keep pace with the health of the enemies (fish) for a while until it slows down, it slows down almost immediately with the second or third fish, and there's no way to stop yourself from exclusively fishing them up, so progress slows down quite a bit.

As a fatty game:
Nothing here, really. If the girls gain weight, I can't tell, even though the game only feeds the rightmost girl because of a programming oversight. I hear there's a fat mermaid or something later in the game, but I didn't see it.

Bugs:
There's a few here and there, mostly little ones like the health bars not fading out correctly or whatever, but there's a BIG glitch. I, and other people, have noticed winning against the holy mackerel causes the game to crash, thus locking you into level 5.

I was going to write other stuff, but decided I'm making this review too long, so the TL;DR is that it's an okay, but very flawed clicker. PROBABLY not worth really playing unless you're a fast clicker like me, but ehhhhh, nah.
