Halcyon for iOS

Halcyon is an innovative game that challenges you to join like circuits together while keeping unlike circuits apart by making links between strings. As you pass one test, a new, more challenging one is presented, and the musical accompaniment helps to create a surreal atmosphere as you work your way through the levels.

Pros

Straightforward mechanics: The controls of this game are deceptively easy. All you have control over is where you build links between the various strings that the currents are traveling across. Draw a bridge in the appropriate place to facilitate a meeting between two like currents, and then move on to another pair. While this is an easy enough task to perform, the continuously changing nature and positioning of the currents appearing on the screen keeps you on your toes.

Musical component: In addition to the entrancing background music, this app also incorporates music into the act of gameplay. Each time you build a bridge, you're effectively strumming the strings that the currents are traveling on, causing them to emit their own unique pitch to add to the experience.

Multiple modes: There are four different areas that you can play through in this game. You can also choose to play in an endless mode that adjusts its difficulty based on your performance.

Cons

Gets hard fast: Difficulty does increase quite quickly in this game, which may be frustrating for new players. But if you can stick it out, you'll almost certainly be hooked.

Bottom Line

Halcyon is a unique type of gameplay experience. It combines spatial puzzles and music in innovative ways to create a world you won't want to leave and where you'll often find yourself losing track of time. It's free to download and play without limits.
