I had a similar experience but the game I played was called Juggernaut
and that was on the Sinclair Spectrum. Brilliant game I thought then.
I made a tribute to it for the 1995 java4k: Trucker 4K
(So maybe go with another name for yours.)
Regarding you game, it looks quite promising, but I think the controls are a bit difficult to handle. Calm it down. More routes would also make it more entertaining.
r - reverse gear
r - restart
If restart worked it would be difficult to play the game
Also managed to crash bad enough or something, to get this
Color parameter outside of expected range: Green
