Regular YS readers will know all about this, as it was on one of our Smash Tapes a number of months back.
When it originally came out (released by Dinamic through Ocean) there was much disagreement in the office about its merits - divided broadly into two schools of thought, the hey-we're-so-cool-we-can-play-anything hipsters and the I-can't-get-past-the-first-screen sad acts. I fell very much into the second category, as I simply couldn't play it at all, and it was interesting to load it up again a couple of years later and find that, although I had improved (a bit!), I could still get virtually nowhere in the game.
So, let's be controversial about this. People who are really good at the hardest shoot-'em-ups will find this right up their street. I, on the other hand, loathe and detest it. Out of the window it goes!
