Gateway

Gateway is a simple browser-based point and click adventure game, the
objective of the game is to simply get from one room to another, by solving
mini-puzzles within each room.

The blocky protagonist is controlled with the mouse, and can pick up several
objects. These objects can be combined with each other, or used to solve
certain puzzles. Puzzles range from obtaining certain door password codes, to
solving color based puzzles, by stepping on them. The game also features a
hearing aid, which adds text cues instead of playing sounds, and a color aid,
which turns the colors from the puzzles into greyscale.
