The first version was not made for the Spectrum I think.Juan F.

I made some research and it was released in Japan in 1985 (Stop the Express was published in 1983) and both were coded by Hudson Soft, from Japan.
So the first version was made for the Spectrum. In the japanese console version the character goes from left to right (the opposite in Stop the Express). The rest are similar.
Checking other Hudson Soft games I see all are games that must have been converted to arcades (Eric and the Floaters is just great!)
According to Wikipedia the game was programmed for the Sharp X1 first. Which makes sense because Hudson Soft is a Japanese developer.

It was remade for Nintendo Family Computer as Challenger(チャレンジャー) in 1985.
