Infinirail

In Infinyrail you are piloting a City on a train around a cylinder Shaped Land that is submerged in black liquid. The Cylinder is rotating slowly and you have to keep on top of it to not drown. You will encounter the remnants of the things you constructed on every continuous loop. They may be ruined, swallowed by the sediments carried around by the dark tides or something sinister may have started to inhabit it.
