Ancient Ruins

A magnificent castle used to lay here but it chipped away over time and eventualy disappeared. In these ruins there is said to be an invaluable treasure. People have searched and searched for years. All they found was a cave infested with monsters. The treasure is said to be in the deepest part of the cave But the strongest living thing of all time guards that treasure. No one however even got to the monster alive. Feel free to explore here.
(This is my first RPG topic I've made so if I'm doing something wrong tell me.)

Pengfreeze is walking down a path, and notices the ruins.
Pengfreeze: Huh?
Pengfreeze walks into the ruins.

???: Who beith enter here?!

Pengfreeze keeps walking, ignoring the voice.

*A wall falls down on the entrance preventing his exit*

Pengfreeze relly doesn't care, he keeps walking.

There is a door with a lock on and a keyboard with a screen saying enter password.

Pengfreeze creates a block of ice, which he smashes into the shape of a key. He places the key in the lock, then thinks about the password.

???: Tell me your name and I will give you the password.

Pengfreeze:My name? Pengzappy.

???: Thank you.
*The Door opens*

Pengfreeze walks through the door.

The road forks three ways, which one do you choose Left, Right or Ahead?

Pengfreeze goes left.

*There is a pedastal with a huge diamond sitting on top of it*

Pengfreeze takes the diamond.

???: ALERT! ALERT! THEIF! THEIF!
*A wall falls down in front of the exit so Pengfreeze can't escape and and a earthquake starts*

Pengfreeze slips the diamond into his coat and places a false, ice diamond on the pedestal.

An unidentified monster falls down and attacks you.
Monster uses Slash! 10 damage!

Pengfreezes freezes the monster and throws it against a wall.

50 damage! It appears the monsters weakness was ice!
The monster is too dayzed to attack this turn!

Pengfreeze repeats his attack. 50 damage!

The monster dies and the exit to the main hall opens.

pengfreeeze returns to the main hall, and goes right this time.

There is a golden door heavily decorated with heavenly things there.
