Update Didn't Fix It
I’ve had this game since my first iPhone 3G in 2010 and it’s always been one of my favorites. However, I haven’t been able to play this game in several years because of incompatibility with modern iOS. Suddenly, and update comes from the developer several days ago, in 2019, claiming to bring compatibility to the game with modern phones, however the game still does not launch. I thought the developer had stopped working on the game, however that doesn’t seem to be the case, although, whatever compatibility tweaks were incorporated in the latest update were not implemented correctly.
Very original game
I looked at the title to see if it was another TD type game, but it's something very different. You've got to keep your planet safe from a huge alien invasion. To do this you tilt your phone/touch back and forth to shoot them down... oddly enough I couldn't help but thinking about movies about the miracle of birth while playing (you'll see what I mean when you play it).
The game plays fast and the graphics are simple yet very cool and futuristic at the same time. the shooting is easy once you get the hang of it, but it is certainly not an easy game... the challenge is there big time.
For me one of the best features was how they handled the "health meter". In this game you've got a count of how many lives your planet has -- and then you watch it go down as the aliens get past you. It's one thing to see your health bar go down, but another thing all together to see that you missing that one guy just cost 100,000 people their lives! I was really freaking out when I'd realized that I'd already lost over 4 million people! That beats the old health bar hands down!
You also will have different angles on the various levels and you even end up with your planet in the middle and you having to rotate your device 360 degrees to fend off the alien scum. Yes... you will be swearing by the end of the game... but in a good way.
It's a well spent buck and wonderful way to kill some time -- and keep the planet alive.
Easily 5 Stars!!!
Blue Defense is one of the most visually appealing and different games you'll ever see, yet the gameplay which for the most part involves tilting your device is simple. The first thing that struck me when I first started playing this game about month ago was how the visuals remind me of something else...you'll see similar user comments. With the new added levels and sound, Blue Defense and the dev's newest game Blue Attack (what I call the Blue Series) should be in your gaming library if you're into the shmup genre. As you progress through the levels, the orientation and the game itself changes so don't let the screenshots fool you. You'll go from portrait to landscape and vice versa, and soon you'll soon you be holding the device upside down. The tilt controls are highly responsive, and while simple to use, will be tested as you progress through each level. Besides the sound which adds a whole new dimension and feel, you can now choose which level you want to play with, either to start or just to rack up new scoring records. But the dev goes one step beyond simply listing levels...he uses mini screenshots of each of the screens similar to what you would see on your digital camera when you're browsing pics. Like I said, the visuals and design that went into this is what sets the Blue Series apart.
