You enter Room 4. You found the stairs all right. You also found two monsters. One is a blue reptile, with jagged teeth and claws. The other is a green alien with 10 eyes, no 12? No, 15? Well, you don't have time to count, or you may end up dead. You quickly slice off the reptile's head and stab the alien. But luck isn't on your side anymore. The sword stabs the alien, but it breaks in half in the process! The alien slumps to the floor as you throw the broken sword to the side. With grandma right behind you, you head towards the stairs.
Head to the first floor on Chapter 20.
