Knight Guy in Low Res World: Castle Days is a homebrew action platforming game for the Atari 7800. You play as a knight who decides to go into a castle to rescue their pet from a dragon. There are 99 rooms of danger and puzzles to go through if you are to get to your pet before an hour is up and you lose completely.
MrTASer and Samsara collaborate to go through all 99 rooms and defeat the dragon as fast as possible. A cat was also chosen as the knight's pet.
