Sunman is a single-player action platformer similar to Sunsoft's famous Batman game for the NES/Famicon. It originally was to be released as a Superman game, but then Sunsoft lost the license and reworked the game into Sunman. Despite this, the game wasn't even announced and was completely lost until a prototype was leaked online.
