Clockwork knight 2 (Sega Saturn, 1996) - review 

corrections after editing
you can play as Ginger but only as a cheat code, point was to add new content by doing things in-game. game has some of this but felt kind of cheated with just "cheat codes"
boss rush is here with all bosses but again you get an extra fmv beating them on the hardest difficulty. seems lame imo
anyway hope you enjoy
