We gave the game a solid Gold Award in its review, saying, "Shadowmatic boasts the same kind of chill out gameplay that doesn't focus on winning so much as delivering a mesmerising experience. You play this game to relax, not to shore up high scores or indulge in OCD-level exploration."
If you've missed the Shadowmatic train, it's an atmospheric puzzler where you have to rotate abstract objects to cast a silhouette on the wall. Personally, I dive into it every now and again to just chill out and enjoy discovering the different forms.
The 'Other Worlds' chapter features 33 new levels across three thematic environments: Ancient Worlds, Music, and Space. Though there's no world on the Android version just yet, the update lands on iOS on April 19th (this Thursday).
