Didn't get the theme incorporation concept but does absolutely everything right in this genre - gameplay, sound/bgm, graphics & challenge. Loved the BG score times 2:-). Took a while to realise I need to ram into the reds since I cant shoot with the shield surrounding me. Got to the laser-line-shooting enemies and I just couldn't get through. The music was relaxing enough to keep me trying so many times, but in vain. Sweet game. Sweet BGM.
