Take a moment to get into the game, galam.  It's really quite catchy.  I don't own it; I've only played it via flash hucard, but it's a decent challenge and the graphics they pull off, from a technical standpoint, are pretty impressive for a hucard.  The music will stick to your brain.  Overall, it's a game I'd love to find for what I've spent on most PCE shmups (<$50, usually around $20).  It's a shame it goes for so much these days.
