Spark is a character owned by LakeFeperd (Feperd Games) and makes a cameo in Indie Pogo. He comes from the game Spark the Electric Jester.
"Spark entertained many in his career as a jester...that is, until he lost his job and was replaced by a robot version of himself, Fark. In a strange twist of fate, robots soon began attacking cities around the world, leaving Spark no choice but to stop them." ― Spark's Trophy Description.
Spark is a Formie (an alien species), and an electric jester. His adventures take strong inspiration from classic videogames such as Sonic the Hedgehog, Kirby and MegaMan X.
The adventure itself was a passion project following the creator's prior work using the Sonic Worlds engine: Before the Sequel (taking place between Sonic 1 and 2) and After the Sequel (taking place between Sonic 2 and Sonic 3 & Knuckles).
