Playskool's My First Shmup
Breezy game you can beat in an hour and platinum in two that combines both horizontal and vertical sections and has an overarching ship upgrade system that makes destroying everything in a level to get credits more fun.
Some bafflingly bad music though. I mean literally a playlist of maybe six songs, one of which has to be an eight second loop, thrown on shuffle every time you begin a level.
