Dark Void Zero

As the '80s were drawing to a close, the developers at Capcom began work on a top-secret project that aimed to set new standards for the platformer genre. That game was called Dark Void. Alas, Capcom suspended development on Dark Void as it began to evaluate the SNES. Before long, the game was shelved and drifted, unnoticed, into the annals of gaming history. (gamefaqs)
