Still putting together the gear system.

- Gear has 4 types (currently): Weapon, Armor, Ring, and Pet.

- Armor will change the appearance of the character.

- Pet will follow behind the player.

- Ring has no visual aspect, just provides stats or whatever other effects they'll have in the future.

- Weapon currently gets displayed in the player's hand, based on the equipped weapon

Will be adding additional gear items next, and allow the users to equip/unequip gear. After that, gear will be added to the shop stages that already exist.
