User summary (details from Wikipedia):
Cosmic Causeway is an abstract racing game and the sequel to Trailblazer written by Shaun Southern. It plays mostly the same, though the sequel lacks the 2 player split-screen mode and has some more advanced features.
The player guides a ball travelling across a 'road' (into the screen) with holes and differently coloured squares and must reach the end of the stage without dying or time running out. Travelling across certain coloured squares will cause the ball to jump, speed up, slow down, bounce back or other effects. The player can also jump on accord.
