No one had written or done video about this game in English or Japanese when I picked it up about 5 years ago! Game is completely buck wild and will gave in your skull trying to figure out exactly what you are doing. Would not call it a rail shooter, outside if the technicality that you are literally on Rails and shooting.
Anyways Ps1 has a lot of these games
Cowboy Bebop
EoE
Gamera 2000
I’ve played Planet Harriers and outside of the nurse with the surenge you ain’t missing much!
