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 |
Another cool "game" to get inspiration from:
