How to get every ending

A tip for exploring the story

On your first playthrough, don't worry too much about exploring alternate dialogue choices or events - you'll unlock an ability after achieving Ending 1 which will make exploration much more straightforward.

If you've already gotten Ending 1 and are looking to use the ability, here are some hints:

• Go for ending 3 or 4; the ability is revealed in-game during these routes.
  
• Try pressing various buttons on your keyboard
  
• Press Left Shift

In all future playthroughs, you can skip waiting by pressing Left Shift. Careful not to spam it, or you'll miss dialogue where Aliya keeps going if you don't respond! Keep in mind the skip ability does not work for anything post-ending in Ending 5; that is, the daily events.

Ending 1: "The Truth"

This is always the first ending you'll reach - the other endings require information you'll find in this route.

Tips for your first playthrough:

• Kane's survival won't affect the ending, but if you want to save him the first time pick second intercostal space.
  
• The order you tell Aliya to take care of the three issues with the ship won't affect the ending but will result in slightly different situations and dialogue. One particular change of note: Aliya will want to move an important sample in the incubation chamber. If you take care of the engine problem first, or don't let her do this, there'll be a slight dialogue change which foreshadows Ending 1's major reveal (the bunny dog dies due to spending too long in the cold, leading to Aliya discussing clones with you, and whether clones are truly unique, living creatures).
  
• Missing the first engine burn timing window will likely only result in missing out on some dialogue about Aliya's past; but missing the second window will lead to a game over, so be careful.

With the two pieces of information you receive at the end - Aliya's codeword "hyacinth" and the warp drive key 0XA89BC52E - you'll be able to restart and get the other 4 endings.

Ending 2: "Return to the Gilded Cage"

• When given the opportunity, do not use the code word to introduce yourself to Aliya
  
• Guide her through repairing the ship
  
• When she says she doesn't know what to do next, suggest using the warp core with the key you found
  
• Once she gets through the security locks, give her the key - 0XA89BC52E

Alternatively:

• Introduce yourself using the code word
  
• When the ship is repaired, don't tell Aliya about her father
  
• Encourage her to return to the company

Ending 3: "Hold on to the Final Happiness"

• Give Aliya the code word
  
• When the ship is repaired, don't tell Aliya about her father
  
• Encourage Aliya to investigate the signal
  
• During the dialogue, tell Aliya's father that she's a Doll exploring space for the company

Ending 4: "Embrace the Journey of Fate"

• Give Aliya the code word
  
• When the ship is repaired, don't tell Aliya about her father
  
• Encourage Aliya to investigate the signal
  
• During the dialogue, either don't interfere, or encourage Aliya to go on living

Ending 5: "Pioneer a New Path"

This one's pretty straightforward:

• Give Aliya the code word
  
• When the ship is repaired, be honest with Aliya about her father

Achieving this ending unlocks daily events.

Nope, saving Kane doesn't affect anything.

Yes, there is more content, not sure why it's not triggering for you. I recently learned (recommend not spoiling this unless you're having issues with the dailies) you can skip daily content as well using Right Alt instead of Left Shift .

so I guess saving Kane or not never plays a part.
Is there anything in the 5th ending after the assembly the resistance was having? I waited over 24 hours for a response with me saying "Keep in touch" and her saying "absolutely" and it didn't progress, reset the game to get the other endings(when I was doing it without guide, that was my second ending), but now I came back to it and the pressing Shift isn't working on skipping to the next dialogue.
