Trainyard. Control the switches to get your trains to the right stations. A new game for Commodore PET/CBM, Commodore 64 and Commander X16.
Although I have now written 13 Commodore PET/CBM games and ported a few of those to the Commander X16, this is my first time writing a game for the Commodore 64. And it is also really the first time I've worked with colour, pixel-level graphics and sprites on an 8-bit machine. Hope you enjoy the game no matter what platform you play it on!
