Oh, when I said "maybe not the most creative take", I meant as in it doesn't have to blow your mind 10 times over, it's just a pretty well executed game. Recycling ammo is still a cool idea though! Besides that, the game does definitely have its unique identity with the vampires and everything. On that note, if you want to develop it further, you could probably go all out on recycling. Maybe you could have different weapons that share bullets, a type of bullet could ricochet around a few times before dropping to the ground, you could swap between your bullet types, etc.
As a side note, I just remembered this, the game can be a bit too dark in some areas.
