I'm just gonna shill my favourite shmup. It has well implemented dynamic rank - when you play well & try to push for higher scores, the game fights back and becomes super hectic. Nice FM synth soundtrack, and some of the later ships play really differently. I'm always a fan of gimmick ships in shmups.
