If you've played the (sadly no longer available) port of SpaceChem or the rail-drawing puzzler Trainyard, Perfect Paths may feel familiar despite its potential confusing UI and mechanics. Much like those, this is a methodical logic-based puzzle game, challenging you to splice together nodes amid limited space.

At its most basic level, your goal is actually quite simple. All you have to do is move the colored blocks onto the similar-colored tiles on the grid. This is a game of step-by-step planning, of counting turns and meticulously setting up your commands and paths. It's the kind of game where, once you know how all the elements work together, you could succeed on your first try if you think ahead and consider how and when and where each move will affect the next.

Perfect Paths'...paths occur in increments, designed around intervals of commands and letting you design each step carefully.. You can make blocks move in various directions, push each other, and make them link together and disconnect by passing over special icons.. The early levels are easy, but soon more mechanics are layered on and the simple obvious solutions won't work. Synchronizing paths, figuring out where and when to make blocks interact with each other, while still allowing them to reach their own tiles, watching your carefully-designed array of commands in motion are what makes solving a level in Perfect Paths challenging and satisfying.

Perfect Paths is available for $1.99 on the App Store.
