Works for me in Firefox but not in Chrome. (Looks like it might be an issue with the engine.) Not bad, but really hard! I played several times and never made it that far. Keeping track of two ships at once is killer. Tip: you can do pretty well by just leaving both ships in the center.
Desktop version ran OK, but people don't like installers (too many games to install and play!)
Sound and art decent.
Game mechanic of mirrored dark/light enemies/shots is cool, but been done a few times. Legitimately fun though.
