The Court Jester is a 2.5D sidescroller made with the Unity game engine. The game stars Domitian, a court jester who seeks to kill the emperor in order to seize power for himself. But when his plan nearly gets him killed, Domitian makes a pact with a fallen god who grants him powerful magical abilities to help him seize the throne. To reach his goal, Domitian must traverse a brutal world where allies stab you in the back, priests hurl fireballs from on high, and gods and emperors alike are savage killers.
