okay I'm actually kinda lazy so the control scheme is as follows:
you select items from the inventory then press W to equip
equipped items can't be scrolled through as they are separate from the inventory (I don't like it but it's the only easy way, I want to ship a game..)
buttons 1-5 are to unequip items, (1 is weapon, 2 is quiver, 3 is helmet, 4 is armor, 5 is accessory)
it sounds really weird I wonder if it'll be comfortable
