IndieGames.com: "Judging by the comments thread on our VVVVVV review earlier in the year, there are a good number of indie gamers who didn't partake in a bit of VVVVVV action due to the $15 price tag. However, now you have no excuse - Terry Cavanagh's gravity-flipping platformer is now available on Steam for $5.
In fact, for the first week there's an additional 10% off, so it's even cheaper than that! Seriously now, if you haven't played it before, you must do so - it's one of my indie games of the year so far, and a lovely way to fill a few hours. The game was also nominated as an IndieCade 2010 finalist recently, which may have been that extra push Terry needed to convince Valve to bang his game up on Steam."
