CoffeewithGames shows Cave Story's debut play-time data.
CwG says in one section, "Cave Story released on Nintendo's WiiWare service on Monday, March 22, 2010."
Ending it with, "It took approximately 85 days for Cave Story's data to debut on the Wii's Nintendo Channel."

Cave Story+ is free at Epic Games Store. The free game offer runs until September 7 at 11 AM Eastern. Once you claim it, it's yours to keep.

Alex S. from Link Cable Gaming writes: "Last week we took a look at ten games that, while great in their own right kind of represented what most people think of when they think of DSiWare; small games that offer fun, but limited experiences. And while that's definitely a defining feature of DSiWare games the service was also home to some surprisingly deep experiences that you can take on the go. And that's really what defines the best games for the service, games that went above and beyond what people expected from it."

Starting today, Cave Story+ is free at Epic Games Store. The free game offer runs until December 10 at 11 AM Eastern. Once you claim it, it’s yours to keep.
