I thought it would be cool or something if you had different weapons which did a different amount of damage, swung speed and so on. Just wanted to bring it up :P
Maybe chain weapons or Funny goofy ones like you hold a mini trex (bow re-skin) and the arrow is a little roar
Maybe even shields
I think that weapons that were on the hands, like brass knuckles, would be cool.
You technically already created a grenade...
Guns like maybe shotguns that you have to manually reload, or maybe stun guns.
Maybe cannons in the walls? So that would make you get a projectile weapon like a bow or a gun.
Maybe a Spear that has longer reach but no horizontal attack.
A Battle Axe that swings slower but hits harder and unbalances enemies when they block.
A Boomerang type weapon that can be thrown at short range but leaves you defenceless until it comes back
