Nice game - I tried to use the arrow keys for controls, but found I needed to rotate the keyboard.  Perhaps consider the mapping:

  • D (right arrow): advance
  • W (up arrow):  left
  • S (down arrow): right

Specifically, the code changes are:

v0 := OCTO_KEY_D
if v0 key then px += 1

if px == 64
then :call moveplayer

v0 := OCTO_KEY_W
if v0 key then py -= 1

 v0 := OCTO_KEY_S
if v0 key then py += 1


I considered that, but decided I  wanted to have the controls  be from the viewpoint of the car as WSD feels kind of weird.
