I like this type of games
Graphics - I like most parts of it but some enemies have wierd shapes. One of them looks like a luggage another looks like a triangular beetle...
Style - I like this type of games so I put style high. Add powerups to the game and other weapons, take away the laser thing before the enemy shoots in the first level and dont make the explosion of enemies/ bosses damage you severely! If you really want that, dont make your fighter unable to move when the boss explodes!
Sound - I didnt like the music. it kept looping on and on... But the sound effects were good.
Violence - Nothing to say here. Theres no violence.
Interactivity - Make your fighter able to move at all times. even if the boss is setting itself up. don't make your fighter freeze there. And also when the boss dies. dont make the fighter freeze then and wait for the explosion to kill you.
Humour - ... Nothin to say.
Plz make a sequel!!! This type of games are what I like most! I totally loved to play Raiden
