Jester is a cancelled platform game that was in development by Sega of America for the Genesis / Mega Drive. There is not much info on its gameplay and only few levels backgrounds are preserved in the gallery below. Jester was canned after a problematic development and it is unknown how much was completed before the cancellation.
Thanks to Alan for the help in preserving some media from this lost project!
Thanks to Jason for the english corrections!
