One Dog Story (UP)

Spoilers ahead.

There are 5 endings to the game. In most cases, you can reload your game after an ending to work towards another one. It will require a minimum of two entire playthroughs to get all the endings though. Below is the requirements for each ending:

#1: When you find the U.F.O, agree to join the alien.

#2: Before the final boss fight, when Albert asks you to join him, accept the offer.

IMPORTANT: There is a glitch in the game (as well as the Steam version) in which the default button to progress dialogue () will inadvertently make a choice for you. In order to properly make a choice during the dialogue after the final boss fight, press . This will skip all dialogue up to the decision and allow you to make the decisions that will effect endings. If you don't do it this way you will miss out on two endings.

#3: After the final boss fight, you will have a choice of staying in the present or returning to the future. If you refuse to go back, it will unlock this ending (this is choice 'B' and will always be the ending if you don't use the method above using )

#4:
-You must save Flick (give him first aid kit). Not 100% sure this is required, but he does give you a crystal for the machine.

-You must let EO-42 (the other dog) die after that boss fight

-After the final boss fight, when giving the option (pressing to get the options), choose the 'A' option to go back.

#5: (The Best Ending)
- You must save Flick. Again, not 100% sure it is required, but doesn't hurt.

- After the fight with EO-42, spare his life.

- After final boss fight, choose the 'A' option to go back.
