Necro Gaia is a short arcade defense game from Lazy Brain Games, creator of a few other freeware indie games such as Mecha Spider Island and Infernal Edge. This intense little release puts you in control of a small blue planet called Terra, a lovely little Earth-like rock orbiting a sun that is traveling to another galaxy. You have to stay along for the ride, but the trouble is, all sorts of dangerous things are floating in the blackness of space. By changing your orbital position as well as summoning some temporary planetary friends, you can help Terra survive her journey to her new home, defeating the all-consuming Necro Gaia in the process!
Necro Gaia controls using just the [spacebar] to orbit and the mouse to drag and drop planets from your inventory. Some planets fire shots, other offer health or other tactical advantages. Either way, you must collect crystals to keep your mana full, as placing planets can be a costly affair. In addition to all of this, Terra casts a long shadow in space that slows down enemies in its gaze. This can be useful for halting oncoming asteroids or, hint hint, making certain enemies vulnerable to attack. We'll leave the rest for you to figure out!
Necro Gaia offers a whole lot of solar orbiting and planetary defending, all playable with a few buttons and absolutely no hassle. The experience only lasts about ten or 15 minutes, but it's a tense and expertly paced experience that will make you feel like a planetary hero once it's all over!

It's not easy to beat, but it's really fun to play. It hammers you hard and fast and I think I did better the very first time than subsequent playthroughs.
I really like the red fireball, but I still have not figured out the use of the pulsing green orb or the red planet which shoots out hearts yet.
