posting this as a comment because the latest update contained nerfs and I want to be transparent. I do think that these changes are necessary because it doesn't feel good when you can still eat but you're already at max size, and it makes it more realistic, in a good way I think
scaling has been adjusted so that you need to eat more to reach higher size.
pregnancy has been adjusted with a fixed volume added to each pregnancy regardless of multiples count. this results in significantly larger single pregnancy, with less impact on higher multiples. womb capacity bar has been scaled back by 1/2. this means that up to 6 fetuses could fit on the UI, if such a thing were possible
the adjustment of size requirements means it is more difficult to earn money from streaming overall; some values have been adjusted to compensate (it is likely that more will be needed, probably reduce enzyme cost at least)
this also means that some achievements related to reaching a certain maximum are now more difficult
