Best Of Indie Games: Converging Cathode Rays

[Every week, IndieGames.com: The Weblog co-editor Tim W. will be summing up some of the top free-to-download and commercial indie games from the last seven days on his sister 'state of indie' weblog.] This week on 'Best Of Indie Games', we take a look at some of the top independent PC Flash/downloadable titles released over this last week. The goodies in this edition include a stylish arena shooter that revolves around shooting a biological virus, a zero-button puzzle game, a Flash game that has been described as a blend of Passage and How to Raise a Dragon, plus a new tank construction game from the ever-prolific Nitrome. Here's the highlights from the last seven days: Game Pick: 'FoldingStory' (FoldingStory Team, browser)
"FoldingStory is a digital version of the classic classroom collaboration story game, in which participants take it in turns to add the next line to a story until the whole thing is complete. However, each player can only see the last couple of lines, and hence have no idea how the story goes before that point." Game Pick: 'Bio Guardian' (Oniric-Factor, commercial indie)
"Bio Guardian is a stylish arena shooter that revolves around shooting a strange biological virus and keeping the crew of a cultivation vessel safe. These anomalies attack on the way to the planet Nimbos, but fortunately you've got a number of tiny ships to kill them before they can spread." Game Pick: 'Cathode Rays' (Christoffer Hedborg, browser)
"Cathode Rays is a zero-button puzzle game that involves directing a set of coloured rays from one prism to another. While moving the rays you must avoid letting beams of different colours touch each other, else you'll be forced to play the same puzzle all over again until you get it right." Game Pick: 'Convergence' (Streetlight Studios, browser)
"Convergence has been described as a blend of Passage, Pathways and How to Raise a Dragon - minus the scales, it's a pretty good description for this surprisingly deep Flash game." Game Pick: 'Steamlands' (Nitrome, browser)
"Steamlands is all about building tanks, Captain Forever-style, and laying into anyone who decides to take their own mechanical wonder for a spin. Each level requires you grab pieces with your mouse, tack them onto your tank, and roll towards the enemy all guns blazing."
