Cave Story 3D is a Metroidvania platform-adventure game developed by Nicalis and published by Nippon Ichi Software.

Due to the game having been published by Nippon Ichi Software, the player is able to unlock a Prinny Cap item by getting the best ending.

While Nicalis founder Tyrone Rodriguez posted in Miiverse that the game would be coming to the Nintendo eShop in late 2014, it ultimately never received a digital release.

[1] Hollander Cooper of GamesRadar+ rated the game 4.5/5 stars, saying that while people would likely react with "disgust" to the new 3D graphics, it would be "a shame, because Cave Story 3D is absolutely remarkable".

Saying that "a majority of the new content comes in the presentation, which has been built from scratch for the 3DS", he states that the visuals take "full advantage of the system's capabilities", and that "the audio, too, has been reworked with great success" compared to the game's WiiWare version.
