12 rounds are not even remotely enough. The MiMC paper says you need ceiling(log3(p)) rounds for e = 5 (that's not a typo; definitely log3), and ceiling(log7(p)) rounds for e = 7.

Yup I 100% agree here, 12 rounds are not enough.

On my todo list is to increase it significantly.

There is a very practical attack against 12 rounds which requires only 128gb of RAM.
