After a long hiatus, Zack Livestone is back to take us deep within his chalky, imaginative world filled with perplexing puzzles and captivating characters. Enter the stark world of Deep Chalk 4, the latest installment in his Deep Chalk series and arguably the most elaborate and deep experience yet.

In the third episode in Zack Livetone's series of abstract point-and-click adventures, you once again accompany a floating crystal through a world of photographic landscapes and chalked-in plantlife, coaxing various bits and tibbles into place in order to solve puzzles. Some objects need to be pushed, some clicked, some nudged. Turn up your speakers for this.

Deep Chalk: Second Phase is the continuation of the journey of the crystal, the player character introduced in Zack's black and white world of the original Deep Chalk. The objective is the same: discover the secrets hiding beneath the surface and escape. While you're there, enjoy the quest; be inspired.

Deep Chalk, from game author Zack Livestone, is a charming and interactive point-and-click, in which you clear the way for a powerful crystal to escape its confines, presumably to reach a higher plane of crystallinity. Its interactive Samorostian landscapes are augmented wonderfully by ethereal music clips to produce a deep, if slightly dry, experience.
