How many endings have this game??

Their are 2 parts in every ending. The items you are getting to fill your box is known as momentos, will influence the first part of the ending, the conversation with Dr. K and Harry busts through the door :O.

-The First One is that Cheryl forgives Harry and they hug (All Happy :D), collect all or most of the momentos to get this part.

-The Second One is that Cheryl does not forgive Harry and refuses to be hugged by Harry (Ouch Rejected :O), collect a fair amount of momentos to get this part.

-The Third One is that Cheryl refuses to believe Harry had died and he will always be her hero (Aww Despite this being a lazy ending, I like this one the best :D) collect a low amount or not a single momento to get this part.

The first part will always end with Harry freezing over :(, Talking with Dr. K and answering his questions and undergoing his therapy will influence your path towards your ending as well. Not to mention your gameplay will also influence your ending for example staring at semi-nude posters will influence you more towards the sex ending (o-o).

They're are a total of 5 part 2 endings in the game and it is as listed:

"Love Lost" ending- Be a good guy and devote yourself to finding Cheryl, avoid looking at sexual posters and/or alcholic drinks. Be sure to check the "I make friends easily", it will help alot.

"Drunk" ending- Be as drunky as you can be :D, pick "alcohol" related topics and answers when the Doctor asks you and look/zoom in at the Doc's drinks and other beer bottles that you come across in your gameplay. Be sure to check "I prefer a stiff drink", it will help alot.

Sex ending- Basically being perverted enough such as answering the Doc's questions with sexual related stuff, picking sex ed to be in your scheldule, and zooming into semi-nude posters. Some posters such as the "butterfly" woman can help as well although the women presented there usually are well dressed. Also check the "I had cheated on my partner before" and "I enjoy foreplay during sex", it will help alot.

"Wicked and Weak" Ending - Simply be unfriendly to everyone and answer the Doc's questions with unfriendly comments and be sure to check the "I don't make friends easily", it will help alot.

UFO Ending - Take a picture of all 13 ufos with your phone, that's all there is to it.

Once you arrive at the Hospital, Cybil will fish you out of the water (not literally), and you will have one of these outfits on. Each outfit will signify which ending you will get, but it is not always the case, it is simply the game's way of saying which ending you are currently going to.

The brown jacket/pink shirt="love lost" ending
The green "kings" letterman jacket="drunk" ending
The long button up khaki coat="wicked and weak" ending

Combine both part one and part two and there is your ending :D.
