Avid gamers among you who owned the original iPhone surely remember Eliss. Created by Steph Thirion and released in March 2009, Eliss was one of the first iPhone puzzlers that wouldn't implement multitouch controls as an afterthought. It went on to win numerous awards and was called by many a multitouch masterpiece. Eliss challenged you to move around a bunch of planets and split/combine them with other planets of the same size/color.
On paper, the concept doesn't sound terribly revolutionary or exciting. But once you picked it up, however, there was no putting Eliss down - it was that addictive. Unfortunately, the creator stopped updating the game just three months following its release: the last refresh was in June 2009.
Turns out other projects have kept Steph occupied - among them a brand new and polished remake of the original Eliss game...
