Nanuleu by Selva Interactive is an excellent new tower-defense strategy game reminiscent of Rymdkapsel. I’ve been a fan of tower-defense games since the original Fieldrunners game launched on iOS just a couple months after the App Store opened. Nanuleu is a less frenetic, more laid-back take on that classic style with many of its own distinctive elements.

Nanuleu is played from an isometric perspective on a procedurally generated map that makes each game you play unique. There are three modes, Apprentice, Warrior, and Sage, each of which is progressively more difficult to complete.

Each Nanuleu map is procedurally generated.

You start each game with a life tree at the center of the map and resources that you can spend to expand your territory across the map. Tapping on the squares on the map that are adjacent to territory you already control gives you the option to plant certain types of trees or simply expand your network of roots. Water, mineral, and life trees can only be planted on squares with corresponding colored symbols and require more resources than simply laying down roots.

Five types of trees are connected by a root system.

After a while, enemies start attacking from different spots along the edges of the map. Planting protector, and later, war trees helps defend your trees against the enemy. As you expand your network of water, mineral, and life trees, resources accumulate faster, but you need to spend your resources carefully to defend your territory. If the enemies start taking out trees, especially those that produce resources, your territory begins to shrink. Vanquish all the enemies and you win the round. If the enemies get the upper hand and overtake your last life tree, you lose.

It’s easy to understand why Nanuleu won an award at the 2015 Indie Game Maker Contest and has already made a best of 2016 list just over a week since its release. The game combines great visuals and sound with simple, but challenging, gameplay. Nanuleu games are not short. Most of the games I’ve played have lasted 20-30 minutes, but time flies because it’s easy to get absorbed in the action. If you enjoy tower defense and real-time strategy games, Nanuleu is worth checking out.

Nanuleu is available on the App Store for $2.99.

After last weekend’s fast-paced, stress-inducing racing game, Neon Drive, I wanted to play something a little more laid back and mellow this week. I found the perfect game in klocki, a new iOS puzzle game that launched earlier this week.

klocki is from Maciej Targoni, the maker of Hook, a well-regarded puzzler that came out early last year. The tile-based puzzle game is singularly focused on revealing itself through its puzzle mechanics and designed to be relaxing. There are no tutorials, instructions, or text. You play klocki at your own pace, discovering the rules organically as you play.

The goal of klocki, at least in the early stages, is to complete lines by swapping pairs of tiles. When you complete a puzzle, you only advance to the next one after you tap the screen. You are completely in control of the pace of klocki, which is backed by a soothing soundtrack by Wojciech Wasiak.

As you progress through klocki, things get trickier. The 2D puzzles gain a third dimension, the puzzles become larger, and the mechanics become more complex, making it harder to work out the solutions. No worries though, there are no timers or score. It’s just you against each puzzle.

klocki, which was featured on the App Store this week, is the kind of distraction I look for more often than not in an iOS game. It’s challenging without being frustrating and as easy to pick up for short periods of time as it is for an hour.

klocki is available on the App Store for $0.99.

Neon Drive by Fraoula is a devilishly difficult 80s-themed driving game that immediately reminded me of the campy short film, Kung Fury. The unapologetic, over-the-top style of Neon Drive is a big part of its charm and adds to the fun of the game, which is available for OS X and iOS. The mechanics of Neon Drive are incredibly simple, but the mastering the game requires precise timing. Well-placed checkpoints provide just enough of a sense of progress though, to make Neon Drive more fun than frustrating.

Neon Drive is part endless runner, part rhythm game. The controls are about as basic as they could be – on iOS you steer your car across lanes by tapping the left side of the screen to move left and the right side to move right. On the Mac, you can accomplish the same thing with the left and right arrow keys or other preset key combinations. Each of Neon Drive’s levels is accompanied by an 80s synth soundtrack that adds to the game’s atmosphere as you dodge obstacles. The first time you hit an obstacle, your car is temporarily slowed down with the screeching sound effect of a needle scratching across a record that distorts the soundtrack. Hit a second obstacle and it’s game over. Fortunately, if you cross a checkpoint, you don’t have to restart from the beginning.

Neon Drive features seven very difficult levels. Getting past the first level felt like a major accomplishment even in normal mode. I’m not great at games that require perfect timing, so your mileage may vary, but despite the difficulty, I found Neon Drive fun and addicting in the same way a game like Canabalt is.

Neon Drive’s look and soundtrack are a big part of its appeal.

I played Neon Drive on my iPhone 6s Plus, iPad Pro 12.9, and 2015 Retina MacBook Pro. The games are virtually identical on iOS and OS X, but I’d give the edge to the iOS version because there’s something about tapping the screen directly that makes Neon Drive a little more immediate and fun. On OS X, Neon Drive got my laptop’s fans roaring almost immediately, which detracts the game some. My one wish for Neon Drive is for Fraoula to bring it to the Apple TV, where I think its simple mechanics would work well with or without a controller.

Despite being frustratingly difficult to master, Neon Drive is a blast to play and does a fantastic job of making you feel like you are playing a real 80s arcade game.

Neon Drive is available for $3.99 on the App Store and $9.99 on the Mac App Store.

Perchang is a physics-based puzzle game from a new indie development shop that goes by the same name. Perchang describes its game as Lemmings mixed with Marble Madness, which is apt if you’re old enough to remember those games, but that description doesn’t do Perchang justice.

The challenge of Perchang lies in its puzzles, not its controls, which makes it easy to get started, but hard to master. Each of the 60 levels require you to guide tiny balls into a goal using fans, magnets, flippers, portals, and other contraptions. To further complicate things, you’re racing against the clock to get enough of the relentless stream of balls into the goal before time runs out.

The gizmos you use to guide the balls in Perchang are controlled by two on-screen touch points – one red, the other blue. The colors correspond to the items you are controlling on the screen. Touching the colored contraptions on the screen toggles their color, which changes the touch point that controls them. It’s an interesting touch that adds extra depth and strategy to each level by giving you an additional way to approach the puzzles.

The visuals in Perchang are stunning. Each level features beautifully-rendered 3D contraptions. Only the interactive items are colored to correspond to the colors of the controls. The spare use of color is striking and adds atmosphere and personality to Perchang, while also helping players focus on each level’s goal. There are so many variables that affect each puzzle, it’s easy to get lost in the harder ones for long periods of time testing different strategies, which is precisely why Perchang is so much fun.

Perchang is Universal and available on the App Store for $1.99.
