2.5D endless procedurally generated train conductor sim Cab Ride

https://powersaurus.itch.io/cab-ride

Drive a train, forever, through a dreamlike land.

Transport passengers to their destination.

Watch the world go by.

Listen to chilled out chiptune music.

In Cab Ride you can drive thousands of different train routes through rolling hills, winding tunnels and weaving between the tall buildings of vast cities. You can drive the train for as long as you like. When you're ready to end your journey, hold down the left arrow key to announce the last station. Stopping at stations along the way means you can pick up and drop off passengers. Try and stop at the marker at each station for a high rating. Or don't! It's up to you.

Cab Ride is a casual train simulation, not aiming for real world accuracy, but like a real train, it takes a while to brake. If you're overshooting stations, watch for the alert for the next station and reduce the throttle so you're ready to stop.

Hello! It's your turn to operate the scenic railway. The local town cats would love to join you for the ride too, if that's ok.

Short Trip is the first instalment in a collection of interactive illustrations created for the web. It has been created as a study into capturing the essence of graphite on paper within a digital context, and to learn more about web-based graphics technologies. Short Trip will run on most devices supporting WebGL, including mobile devices.
