Cave Story will have three save files and updated graphics and music. The game's original PC graphics and music will also be featured as a bonus. The Classic Controller will be supported, and the game will have three difficulty levels: easy, normal and hard.
There will also be support for downloadable content, with Nicalis possibly taking requests from fans. The game will also feature an updated script, with permission from original creator Daisuke Amaya.
After further apologizing for the game's delay, Nicalis ended their blog post by offering special holiday remixes of Cave Story's music by Dustin Kulwicki.
