Really good use of theme. The writer shows a good talent for narrative design with how things are placed, I especially like how things are presented out of order to reveal the whole story as time goes on. Ending was a bit abrupt and sorta felt like a glitch. Otherwise, this is VERY atmospheric and very well done. It brings me back to a feeling I thought I left behind in my old MMO days and it's just heartcrushingly good at what it does.
On a technical level, I like how this game did a lot with Flixel's out of the box tools. Very liberal use of FlxTrail and done exceptionally well when it's used, this is the sort of stuff I like to see where you take some pretty straightforward art and move it up a notch with effective use of default Flixel FX.
