This game was originally released with a bug in the timer in round 13, you only have 30 seconds to complete the round, which makes it impossible to beat, so Poke 43006,195 and Poke 44490,0 has been used for unlimited time for level 13-16, but it is also possible to enable Trainer mode at the intro for unlimited time for all the rounds. The game loops after round 16.
Metro-Cross is very similar to Ninja Scooter Simulator, which was also released in an updated 128k AY version in 2020. See that game here: https://www.youtube.com/watch?v=f8FOCLwSijE
