Sewsack: Salvation is game created for an unknown system. It follows the adventures of Sewsack, an escaped government experiment who hides in a libarary. Most of the missions are open-world but feature lots of platforming elements. As the game goes on, the military gets involved and eventaully Sewsack has to constantly keep running from them.
Sewsack can preform a triple jump and wallclimb as well stick upside (he can't walk on the celiling though), and can preform melee actions with his claws.
