Trying to remember a game I saw a review of once in a magazine. Every effort to search for it has failed. I wanna say it was Sega CD, but might've been another platform. It was, I'm, pretty sure, a rail shooter (in the sense of literally just aiming as you automatically traverse a path) and it had anime cutscenes and a female protagonist. The magazine specifically mentioned a shower scene, as I recall. The enemies were kinda arthropod-looking machines, possibly specifically insect-like.
