The Bridge

The Bridge is a 2D logic puzzle game entire in black-and-white based on physics and warped perspectives similar to echochrome or the works of M. C. Escher. The game contains 48 puzzles divided over different chapters. The goal of each puzzle is to enter the door that leads to the level exit. Some of them have locks and then one or more keys need to be retrieved first. The levels are accessed from a house with different floors.

The main character can move left or right. Two additional commands allow the player to tilt the game world left or right and then gravity comes into play. By rotating the world, different surfaces can be used, for instance using the ceiling to walk once it is upside down. This is for instance used to move objects, move keys and get hazards out of the way. When a mistake has been made it is possible to rewind time.

Most of the puzzles are based around specific shapes and types of architecture, but each of the four chapters introduces a new mechanic. There are gravitational vortexes that suck loose objects inside and can be stopped by moving an object on a button. Other levels have inversion where a white version of a character can be created at specific parts of levels, allowing him to follow a route that is logically not possible with the perspective. Another one has parallel worlds on top of each other accessed through doors. When the main game of 24 puzzles is completed, alternate versions of all puzzles are unlocked with a higher difficulty level and an alternate ending to the game.
