Corrected the first line. (The genus should be assumed to be at least 2, as in the question further below. For tori the answer is 4 critical values, and this is realised by the Weierstrass p function.)

Apr 2, 2021 at 16:31 | comment | added | abx | You just need to apply your argument with a Weierstrass point — that is a point $p$ for which there exists a meromorphic function with a pole of order $k\leq g$ at $p$ (they always exist). Then the number of critical values is at most $2g+k\leq 3g$. | |
