Spirilon is a horizontally scrolling shooter with strong Uridium influences and some rather nice graphics.
The single level demo features an organic-looking ship, across which the players ship flies back and forwards. The long level is 7200 by 144 pixels in size.
Spirilons titlescreen mentions Ocean although this does not mean that its a long lost game from the famous publisher. Artist Angelo Bod mentions that Ocean was approached at one point but this would have most likely been one of a number of potential publishers.
The game was roughly 70% done with the programming side furthest from completion.
