Preparing for the FCE. Please, could you correct it?

THE MAN WITH NO FACE

I pushed open the door.The house was empty, (You need a comma between sentences separated with a conjuction) but I could see that someone or something had been there and had only just left. I nervously came into the house on tiptoe little by little,. (You are starting a new sentence, so you need somthing more than a comma. Your choices are: 1) a period 2) a comma and the work "and" 3) a semicolon)  I was looking for something weird which could help me to know what was happening inside.

Suddenly, I heard a devil shout on the second floor. I went there as fast as I could, (Again, these are two sentences so you need a comma and "and") and when I reached the second floor I did not see anything. I kept walking around the second floor, (two sentences) and then I saw a sign on the ground. It had a hand shape, (two sentences) and it was done with blood. I bent ("bended" is not a word) down to check it, but just then I heard the ceiling to crackle. I looked, at there and there was a mask with no face. I started to run faster than I ever had how I had never done it before (no one would ever say it this way. I think it is how you use "how" the makes it sound awkward). I reached the street, (two sentences) but to my surprise a car ran over me.

Now, I am in the hospital recovering my health and wondering what the hell happened that day. The doctor has just leave just left about five minutes ago. I am alone in the room. -it It is weird, the door is openning slowly ...Oh no!! Oh my god!! It is the man with no face !!! (Unless you are doing very informal writing, it is not correct to have more than one exclamation point)

sorry im in the middle of studying electromagnetic and have no time ,i did as much as i could.

THE MAN WITH NO FACE

I pushed the door open .The house was empty but I could see that someone or something had been there and had just left. I sneaked into the house nervously ,I was looking for something weird which could help me to know if something was happening inside.

Suddenly I heard a devilish shout on the second floor. I went there as fast as I could and when I reached the second floor I did not see anything.I kept walking arround the second floor and then I saw a sign on the ground.It was hand shaped and bloody.I bent down to check it, but just then I heard the ceiling to crackle I looked at there and there was a mass with no face. I started to run as I had never done it before. I reached the street but to my surprise a car ran over me.

Now, I am in the hospital recovering my health and wondering what the hell happened that day. The doctor has just left about five minutes.I am alone in the room. -it is weird, the door is openning slowly...Oh no!! oh my god!! it is the man with no face !!!
