I like the complaining about the game looking linear. Its a DEMO!!! Not the full game. Also love the complaints about the talking magical horse. Giant wolf monsters, vampires and other undead creatures, flying bodiless medusa heads, skeletons, necromancy, and people who can turn into mist are fine, but not talking animals. Magic, why would that be in a Castlevania game?
A little linear-ness is fine with me. Its good when used in moderation. This is a story, it should progress within some kind of order. Its kinda how you prevent players from getting to an area or a boss too soon cuz you might not be strong enough or have the right equipment to prevent being horribly murdered.
My only concern is whether you can lock onto enemies or not.
