Masayuki Ito makes some fine bullet hell shmups on iOS, with .Decluster [$2.99 / Free], .Decluster Zero [$4.99 / Free], and the most recent Bullet Hell Monday [Free] all being fantastic entries in the genre. If you haven't played Bullet Hell Monday yet, or haven't picked it up in a while, the game got an update recently that brings some new content to the game. The big addition is the new endless mode. Once you complete chapter 2, you can now play the game for high scores without any ending. It's a great way to add some replay value to this one, and folks seem to be a big fan of this addition already.
