A lot of happy memories playing this game on a knockoff Apple II+.

To this day it's still impressive to me that they got 3D wireframe rendering (with hidden line removal!!) working on a 1 Mhz 6502 chip - that thing doesn't even have multiply and divide instructions.

And the NES version is bonkers, using sprites to render the vector graphics.

The 6502 has shift left and right.
