Snapshot

Snapshot is an indie platform game developer by Retro Affect. The player controls a character with fairly standard 2-D controls: left, right, duck, and jump. The player also controls a camera viewfinder, the Snapshot of the title, with the mouse. When a snapshot is taken of an in-game object, it disappears from the gameworld and is stored on the camera; the stored images can then be pasted into new parts of the gameworld to overcome an obstacle.
