When I first tried this game out, I found it surprisingly very difficult for a game with simple controls. Although as I kept on going with the game I found it to be highly addictive from it's gameplay to its many characters each with their own theme song. The game series though is made completely from one man named ZUN. The four difficulties give some breathing room on where you lie on the experience scale. The game itself offers three playable characters each with two fighting styles. Each character has their own storyline to play through and with it's four difficulties means it's going to take you awhile to beat every one of them. When you have your character all picked out and you start the game, there's something you should remember playing this game... Your character has a hitbox in the center and it's a little red dot, it's your job to not let ANY bullets touch the little red dot. If you do get hit however don't fret! With correct timing you can use the game's unique bomb system to save your life.
