“When we started on the project back in December, I really wanted to find a way to make 2D characters also work in 3D space. Being a Cave Story fan myself, I thought other fans would probably appreciate it too. Anyway, we’ve spent a lot of time testing and making sure it works right, but now we have 2D characters in the 3D game. This includes the main character, Curly, all the Mimiga– literally every character and boss in the game as 2D sprites in a 3D world. What you won’t see, due to the fact that it’s a new engine and differences between the hardware, are the environments in 2D or the WiiWare sprites and art.” – Tyrone Rodriguez, producer and music director on Cave Story 3D (via D’toid).
