Zarathrusta: 2 Open Source Clones Compared
Both clones come from the same author (Santiago Ontañón) as separate entries in his own Transball series. Super Transball 2 is distributed as a downloadable game with three selectable ships across 15 levels and an auto-saving replay system, while Transball GL can also be played directly in a browser, though that browser version has no sound and its level editor is disabled. Both projects are now halted.
