I love this game. Stretches my brain.
Although I was disappointed when the first thing my brain could work out of a set of letters was 'LESBIANS'. It accepted 'NOREPINEPHRINE' earlier, though, so I suppose I'm satisfied.
My best go was with +2 spread, +4 power/firerate, and maxed duration.
Can't say how far it got me exactly since the score doesn't reset to zero when you restart the game.
With art as sophisticated as this I'm surprised you missed this kind of trivial bug!
3/5
Five stars! This game is amazing and I haven't even finished the optional content!
To everyone getting their saves pwned -- download 9.0.47.0 here http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp9_archive.zip
sConed: it's not a limitation on memory, it's a limitation in Flash. Eventually, there are enough pixels falling that you simply cannot collect them fast enough (incidentally, this limitation appears to be the framerate of the animation.)
Unbelievable. On medium, the only way to survive is to kill everything before you see it-- once something enters your field of view it shoots at you instantly, and you can't survive more than about six bullets. Gets even harder late-game, couldn't finish the last level on Easy there were so many enemies.
And wow, here's a suggestion: force-based impact damage and rebound speed please! Nothing makes me angst more than lightly touching an asteroid and losing the last half of my shields in one go. Or, when I do survive, (especially in Narrow Places) getting bounced around uncontrollably until I subsequently explode.
