It doesn't work at all. Unless you really want to play a half functional game that has totally broken inputs that render it unplayable, just try out a free flash game called Neon2 that's roughly the same as this, only it works, this doesn't.

so i play using a xbox360 controler and the back button is shoot the joysticks are reversed and you need to use the lt and rt to move up or down. this game need to have a controler config

I don't know how to pivot >_>

This appears to be broken, I've killed a lot more than 1000 enemies and I haven't achieved it yet! If you look at some of the achievement tracking sites (e.g. astats.nl) then it appears that no one has received it for over a year. Any chance of an official confirmation that it's broken and, hopefully, a fix?...

please, repair
