I wrote something similar a couple of years ago - https://github.com/adamisntdead/QuSimPy

Happy to answer any questions people have, including on other simulation methods other than state vector!

One of the aspects emphasized in TFA is being able to simulate gates of any dimension/number of qubits (like a 3-qubit Toffoli or a 5-qubit Molmer-Sorensen), instead of just 1- and 2-qubit gates. Have you thought about extending your simulator to support gates of greater than two qubits?

I guess back when I wrote it I didn't see the need given that single qubit gates along with CNOT are universal and they're implemented. I think airing on the side of 'as few features as is educational' was my mentality on this.

I know about the conventional 2-qubit Molmer-Sorensen but not the 5-qubit version. Could I ask what it is?

See e.g. equations (5) and (6) from [1], where any qubit subset of a system might undergo the action of the M–S gate. But definitely the usual presentation of the physics of M–S is on a two qubit system.
