Thanks, everyone! I'm not going to follow a step-by-step walkthrough but I think I'll definitely look up guides for the ultimate weapons and secret characters.
Just got to the Train Graveyard and, having played Remake, it's quite crazy how... quick everything is lol. The pacing here is just constant and it's really cool to see the sheer amount of backgrounds and locations put into such a small chunk of time. Of course the game itself is old, and you can feel it (both in gameplay and in certain scenes...), but with the storytelling on display here I can see why the game's so beloved. Also think there is a certain charm to everything being done by these tiny chibi models with exaggerated acting, instead of today's template of hyper-realistic mo-capped characters.
