Day/Night Cycle: The game now has a dynamic day/night cycle, previously it was only night.
Dual Item Equipping: You can now equip two items and easily switch between them. Keep your melee weapon handy and quickly swap to a firearm when needed (or pickles if you prefer)
Collisions: Walls now block player movement. You can't walk through house walls anymore.
Projectile and Melee Collision: Bullets and melee attacks now collide with trees and walls. You can't shoot or strike enemies through solid objects anymore.
