Ps the The Penrose movement is a bit clunky. It looks weird like it when it's moves. Maybe add more weight to it might help or decreasing its acceleration might give it more of a weight to its movement.
I've talked about this with a few others and its a bit controversial, but the Penrose moving weird is intentional, its meant to unnerve you. Whether it accomplishes that or just looks goofy is debatable, bit for now I'm keeping it how it is.
Also for gameplay, it's already fast enough and has enough mass to be a brutal ramming ship just at its normal speed. Giving it even more mass... I think it would be bad.
The real solution would just be to reduce its manoeuvrability, but if I did that I would want to give it a buff elsewhere to keep it intimidating. At one point I did plan to reverse engineer the reflective shields script from SWP, but given the controversy surrounding that I just decided not to touch it.
