DMG Express
About
DMG Express invites you on a slow-paced trip by train, through a long scrolling landscape, past train stops and vending machines.
You can play it here in the browser, or download the ROM to play in your favorite Gameboy emulator (or console).
Future plans:
At some point I'd like to add background music (v1 is sound effects only), more routes and variant backgrounds. If parallax scrolling makes it in the next version of Gameboy Studio, I'll also add that to the landscape scenes.
