Zeppel Endless

Zeppel Endless is a game where you crew a zeppelin in a endless procedurally generated world, ferrying cargo, making side trips, getting in and out of trouble, upgrading your zeppelin, and in general just tooling around in an airship.

Like most of my browser games its development is on hold, but unlike most of my browser games it's essentially playable.  The scaling of the procedural generation can be unforgiving — the further from the starting zone you get, the stronger and more erratic the wind, which makes flying a zeppelin very difficult!
