‘DMG Express’ is a homebrew Gameboy game simulating a slow-paced trip by train, through a long scrolling landscape, past train stops and vending machines.
It was built using GB Studio, with an export as a Gameboy ROM and an HTML5 version.

You can play DMG Express in the browser here, or download DMG Express 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.
