I’ve just pushed the 3D Vector Space Cab source code and assets up to our github account. Any students of the Vectrex may wish to take a look and see how I typically handle project layout and game state management.
If you just want to play 3D Vector Space Cab on your Vectrex or emu, head over to the freebies page.
Warning to coder readers: I think I used 8-space tabs back in the heady days of 2017! What was I thinking?
