Fun and funky game. Good job.
Player sprites are wicked.
Where the trains moving at random times?
An interesting take on the theme.
Can easily overlook the art and focus on the mechanic. Fun little puzzle game.
Would be nice if there was an indicator as to when the trains would move.
Sometimes different colours would spawn right next to each other, and move onto the same tile at different times, then move off at different times. Quite difficult to plan for.
