Dry martini ,Laboratory password and the Ending

In my playthrough of the game. There is 2 point i got stuck that i would like to share.

Dry martini

I do not get the puzzle with the roman numerals.
I thought the answer is too add up the upper case letter using conversion.A=1 B=1 C=3 etc......
GiN and vERmOUTH.
Which the result is a failure.

The answer is just combine the lower case word.
VIM is the answer.

Laboratory password

Password for the computer in the lab
First i did not want to delivery 3 pigs to Williamson.So i think outside the box and kill all the pigs.
Williamson told me i have fail him and he did not want to talk to me anymore.
I end up killed all the scientist.Turn out the drunken guy have a hint in his dead body.
MALE MEMBER(haha)

Which i did not get it.
The password only need 5 letter.
I typed their name Roche, Juliu , Sarah , Willi , loser.
A failure again.The door is still shut.
Unwillingly,I load up the old save file to start again.
Delivery 3 pigs for them.If you lure the pig one by one. It is doable.

After the labor.The drunken guy will told you the password.

P.E.N.I.S

well play sir

Ending

About the ending.

I got the stuck under the car ending (Vacation man) which i feel bad about it.
I think to achieve the better ending is choose to talk to Philips(THE Warden) about the stranger on two occasion.

• After the fun house
  
• After the stranger put a wire into Harry's body(The player) inside the cave
