Okay, heres a video of me playing the last level of Ikaruga. Now before you watch the video, a bit of explaining of the game will probably make the game easier to understand. First of all its a shooter game, my favortie shooter actually. The game consists of 2 polarities: black and white. This includes all enemies and bullets that are fired. Now, your ship has a shield that can be switched from black to white at will and if the bullet is the same polarity as your shield, it will be absorbed, if its not, well, you die. Also, the bullets you fire also consist of being black or white, depending on the shield's polarity (black shields, black bullets are shot, same goes for white). When it comes to shooting the enemies, your white bullets do increased damage to black enemies, and vice versa (if you've played Metroid Prime 2, its the same basic idea as that). Now the biggest mistake you can make in this game is thinking that its easier because your immune to half of the shots fired. I think it makes it harder because you have to be constantly thinking about which bullets you can absorb (it may not seem hard, but when the screen is covered in them, it can get a bit overwhelming! You will see what i mean when im fighting the last boss). Now that you've got a bit of knowledge on the game, it'll be easier to understand whats happening, if you have any question, feel free to ask.
