“We are all the residue of our past,” Jumagul tells his grandson in the first act of Residue. The platitude sets a bland tone that this side-scrolling platformer never overcomes. While moving from checkpoint to checkpoint, you play as one of three characters: flashlight-shining Jumagul; Emilio, a boy who can jump, swim, and climb; and Nikolai, a man with a grappling hook. Controlling these characters rarely feels fluid, but Residue wants to be less about player skill and more about discovering the nuances of its story. As you pass obstacles and explore the levels, you find various documents and trigger flashbacks of a sort that provide background about the setting and characters. Unfortunately, the game’s sluggish controls often distract from the seriousness of the story; watching yourself struggle with Nikolai’s grappling hook is, at best, bad comedy. The worst scene amounts to the player running Jumagul and Nikolai into each other to “create” a fight, a silly section of gameplay that kills the possibility of believable drama.
