Railbound

Railbound is a puzzle game themed around trains featuring two canine protagonists. In each level, the player is presented an isometric view 2D grid with train tracks, one to four train carriages, and other elements. The player uses a tap-and-drag system to place tracks on unoccupied spaces in the grid, and is given a limited set of tracks per level. Tracks can be placed in any orientation, and can be placed to go straight, turn, or branch. The goal is to place tracks to guide the carriages, each of which are numbered sequentially, in order, to the back of a steam locomotive.

The game's more than 150 levels are structured into sets of stages called "worlds". Each world introduces a new mechanic, such as tunnels or numbered stations, that affects how carriages must be routed. Later worlds combine previously introduced mechanics. Each world has approximately ten base puzzles that introduce its mechanic and must be completed to move on to the next world, as well as additional optional bonus puzzles.

Afterburn is a Polish indie developer which previously released puzzle games Golf Peaks and inbento. According to studio founder Luke Spierewka, Railbound's gameplay was inspired by Mini Metro and Cosmic Express. Its art style was developed from concepts from studio Vile Monarch, and further influenced by French graphic novels. Developing the game's graphical style took up over half of development time.

The game's divide into base and bonus levels was an attempt to appeal to both experienced and casual players. Many bonus levels were designed as modifications of base levels.

Railbound's Nintendo Switch edition received "generally favorable" reviews according to review aggregator Metacritic.

The visual, audio, and interaction design of the game drew praise from reviewers, with most finding that these elements contributed to a cosy, laid-back ambiance. Reviewers cited its comic book-inspired, cel shaded style and warm pastel color palette, describing the art as "cosy", "cute", and "striking". Kotaku generally described the soundtrack as "laid-back", Touch Arcade liked "the little sounds of everything clacking together", and PC Gamer said that "when the piano kicked in in world four I was jazzed". PC Gamer also praised the game's intuitive controls.
