Regarding the hyperspace kamikaze.

I don’t mind it, I think it’s great.
Realistically I don’t think a ship could accelerate to light speed that quickly without killing everyone on board, so we’ll have to assume that the accelerating to “88 mph” works by somehow altering the physics involved.
If a projectile the size of a football would have the power of several nukes, wouldn’t the power still only be directed mostly forwards (and not in all directions like a bomb)? I assume a small projectile would only punch a hole straight through like a bullet rather than “nuking” the target. That wouldn’t necessarily work on something like the Death Star.
