Unfit Knight by Tin Knight Games is a Game for Nintendo-Game-Boy-GB.
This game takes place in the 90s. You play as a 90s kid and play a board game called Nerdy Kingdoms. In the board game You play as a Knight who is well not cut out to be a Knight. And this knight can’t find his sword in his messy room. So he brings a bag of random stuff to fight bosses. And yes this game is very incomplete but there will be more Bosses, Phases, and Story later on. Good Luck!
