The intended purpose of this game is to help induce a zen-like state.
You're a defenseless slow-moving dot, and we're sending hundreds of thousands of missiles to kill you, SO RELAX!
The key is in making subtle shifting movements, becoming one with space, letting your mind be free of the trials of everyday life. ARE YOU FREAKING KIDDING ME?!?! HOW COULD I DODGE THAT!?
This game is composed of several stages, though achievement hunters will become far too acquainted with the easy first one. All subsequent stages are an immediate ramp-up in difficulty, and some are simply much harder than others. It can be unbalanced in the score-based modes, since your second stage could be easy peasy, or what-the-heck difficult. As far as I can tell, stages you complete without dying don't show up in the rotation in subsequent games. If you have the patience, you could complete all of the stages, and see for yourself if there's a reasonable difficulty curve in your next game. They stages are certainly vivid, and could make for some nice screenshots if you're not too concerned about DYING HORRIBLY.
While I appreciate what Borealis is going for, it's just not my thing. If I wanted to relax, I'd watch something, or play a puzzle game or an RPG. If I'm going to be pixel-close to death, I'd rather be playing a 2D shooter. At least that way I'd have some heavy firepower of my own, and can bathe myself in sweet gold whenever I destroy a mega battle-cruiser. I'm aware this completely goes against the design of this game. I'm sorry, but that's why it isn't my thing.
