Two roles, one sketchbook
Linebound is a local co-op puzzle platformer for two players, and the two of you never do the same job. One player is the Artist, who sees the sketchbook from the outside and draws platforms straight into its pages in real time. The other player is Sketch, a hand-drawn character living inside the book, hopping through the puzzles you both create. The Artist places the ground; Sketch uses it. Neither of you can get through a level alone, so the whole game runs on talking to each other about what to draw and where to put it.
How a session plays out
You work through 15 hand-crafted puzzle levels set inside a living sketchbook, with pencil-scratched environments, crayon-colored platforms and doodled creatures filling each page. The loop is simple to learn: the Artist looks at the layout from the outside and draws, Sketch moves across what was drawn, and together you reach the exit. The interesting part is that the Artist and Sketch see different things, so you have to describe what you see and agree on a plan before it works. Expect to coordinate constantly, since drawing the platform is only half the job — Sketch still has to trust that it will be there.
Before you start
Linebound is built for two players sharing one screen, so you need a second person in the room with a controller each. Online play is not built into the game itself; if your group is spread across Discord, someone has to run Steam Remote Play Together or Parsec so the second player can join remotely. The game leans casual and linear rather than open-ended, so sessions move level by level toward each exit instead of giving you a world to roam. The art style and pacing suit groups who want something atmospheric and cooperative rather than fast or competitive.
