Contre Jour is an arcade puzzler that veteran gamers will see as a mashup of game mechanics and inspiration from several other popular titles. That said, Contre Jour is a well-executed melange, a fun and often challenging puzzle game with polished art and sound.
On each short level of Contre Jour, you're trying to get a charming little alien (essentially, a rolling eyeball) to the level's exit. The alien doesn't move on its own, so you need to use attached ropes (some elastic, some not, some with movable anchors), slingshots, malleable ground (which you can shape with a touch), teleporters, and other elements to get the alien to its goal. Each progressive level relies on an increasingly Rube-Goldbergian series of actions, which you must carefully time to get the alien to the exit--ideally grabbing between one and three floating blue lights along the way.
Contre Jour may not introduce a lot of new ideas as a puzzler, but it does a good job of refining some of our favorite ones--and it pulls them all together into an attractive and fairly addictive package. If you're a fan of arcade puzzle games, Contre Jour is definitely worth a download.
