Cave Story has been around for a good few years now, and indeed is still available for free download from the Web.
You may have already played it. You may have already beaten it. Perhaps you even set an amazing time in that bastard hard “secret” level on the way to the best ending. So why would you spend money on another copy for Nintendo’s latest console?
Well, firstly because Cave Story is a lovely game by a talented developer, and is worth supporting at every opportunity. Secondly because the Switch version feels like the most delightfully complete edition of this game there has been to date. And thirdly because this game just belongs on a Nintendo console.
