I know right. Those are my complaints too. But I just jump back on after a while with a new run.
Also the pop-up description on the “multiball” mechanic is that ball level increases the number of balls but as far as I can tell, that only applies to the Matryorbshka ball, whereas all other multiballs just increase attack damage or crit damage.
That’s a really minor complaint but I wonder if they rebalanced it and forgot to edit the text description.
