Increased Difficulty and Monster Variety: Zombies are not only more numerous, but they also differ in speed, strength, and attack style, necessitating frequent tactical adjustments.
Roguelike nature: Each replay includes random upgrades, layouts, and difficulties, making each playing unique.
There are no save points; death means starting anew. If your character is defeated, you must restart from the beginning, increasing the difficulty.
