Cave Story is one of the more iconic indie games out there. Having charming NES-esc graphics, quality chip-tune music and gameplay mechanics the blend elements from the best games of that time period; Cave Story is an indie gem. 
News about it landing on the Nintendo Switch came out in recent weeks and publisher Nicalis released the tweet hinting at a possible retail version of Cave Story coming out on the Switch. 
Bending of Issac is confirmed for a retail release on Switch, so other smaller productions getting retail runs could be a common occurrence on the Nintendo Switch. With programs like Limited Run Games having such success courting indie titles to get retail versions of their releases, we could start seeing a wave of indie retail releases for Switch versions of various games.
