i've found esc pod but the computer refuses to believe it exists. I ask to turn on the lights it aske me why but nothing I say works. I have no hazard suit but it then prompts me to ask about what I found out.

Try the chess program, but don't play a game, pick option #2 That will give you a hint.

1 - More options on how to find the truth. The only way I found out is to ask about astro food, couldn't find another way. There should be a way to either open the window, open the door, ask about the war, or simply being persistent.

2 - There should be a way to choose to stay with the computer. I tried "stay here" and "wait here" "stay" and "wait", but none of them allowed me to end the game by choosing to stay with the computer.

You can stay. Try typing in "I will stay."

I ended up staying with LDAC. I have a weakness for AIs, especially those afraid of dying. Darn them.

To that end, I'd suggest adding a small backstory to the war when asked. How it happened, who won (probably no one!) etc.

Also, asking for options like "Can we fix the navigation systems", "Can we send out a distress call", and "Are the engines still operational" should also yield a response. I'd rather be damn sure that I've exhausted all my options before going for that hard or harder choice.

"Are you lonely?"

It really needs to be longer. My suggestion, if possible, would be to add the ability to move between rooms of the "shelter"/ ship and being able to interact with the computer more before learning the truth. As it is, the reveal came too fast for it to have any real impact.
I have one big problem with the story. At the beginning, I asked about AGS. The answer (Automated Gravity System, I think) made it obvious that I was in a space ship, which I'm sure I wasn't supposed to know yet. You should probably take that out.

as mentioned in previous comments, that the only way to stay with the AI is by typing "I will stay" but typing "Stay here", "Stay with you", "Stay and die", etc. aren't recognised. That was frustrating.

If the game was to be expanded I think entertaining a third option of survival through problem solving with the computer would be the kind of game I'd enjoy but then you'd lose the moral dilemna of dying alone or dying with someone. So... maybe not.

"I will stay" was the only way to stay. Because of that, I thought leaving was the only option.

I also think "Can I bring you with me?" should give a response.

My first time through, I wanted to shut down the computer, so that it wouldn't die alone, then use the escape pod. I don't think this should be an option, but there should be a response to things like "Can I shut you down", "Can I turn you off" and "Shut Down".

same thing later when I asked about my fellow crewmates.

My larger complaint is that after I found out the truth, I waited around to talk to the AI before deciding what to do. When I decided to stay, he didn't recognize the command anymore, so I went to play a game of chess, and it triggered the ending where you don't know you're going to die.

At the beginning on a later playthrough, I tried to confront the robot, telling him exactly where I was when he asked. He used the same dialogue as if I had given a wrong answer. This may have been an artistic choice though,

After I had selected to stay, the AI asked me if I was sure, and told me I would die. I told him I would die either way, and said "let's die together". He didn't know what I meant.

Gets you thinking about what it means to be human (despite the AI's sub-par language recognition)

I think the AI should respond to a question about the engine (or engines).

Before I discover that I'm in space, it should say "What engine? Why would an underground bunker have an engine?"

After I discover I'm in space, it should say "The engines are too badly damaged to fire. Don't you think I would have changed our course if I could? I do not want to die." Or some variant of that.

If you look to the left of the room there is an engine that says AGS. If you ask the AI what AGS stands for and then proceed to ask him what it is doing here, then the AI will reveal to you that you are in space. Furthermore it will give you to options: die with him or take chances. You can die with him by saying I will stay or leave him by saying I will not stay with you.

First say "Hello"
Then say "no"
Then say "give me food"
Then say "esc pod"
Then say "ags"
Then say "why artificial gravity"

The console will then state that you are on a

Then say "what are my options"

You can then decide to die, or skip the next step to see possible questions you can ask.

Make your decision.
"stay"
"leave"

If you decide to not die yet; these all yield different answers that tell you about the ship

Then say "turn on the lights"
Then say again "turn on the lights"
Then say "what was my mission"
Then say "is there another room"
Then say "what structural damage"
Then say "what was my mission"
Then say "where are the others"
Then say "are you lonely"
Then say "why did you lie"

When the computer first told me I was in an underground bunker, I asked it where the others were, to which it responded that they all died. I then asked it "Am I alone, then?" and "So I'm alone?" in a few different ways, for which it had no response. I'd love to see the computer respond with "I'm here with you/not going anywhere", especially in light of what comes after.

a tragic AI.

The cake is a lie?

I couldn't just leave it alone to die, it was so nice to me! D:

LDAC: I know many things about each of them and I will gladly tell you some stories about them. Are you interested?
Me: I'll pass...
LDAC: Please do not use words like that. What did I do to be treated like this?

get some food were only giving me a description of the food dispenser. The hint in the corner was to look around, but since I has already talked about the AGS and the esc pod, the hint was misleading.

"use esc pod" at least 3 times in the end game to get it to let me go. I didn't realize that other wordings would make it open the escape pod faster.

"do you know where you are?" "orbiting a red giant"

uao! this game let me cry. Incredible. I voted it 10 on AG. There are really few games that can make you feel such emotions, and that's only my 2nd 10

I have some suggestions for the game:
Lie to the AI.

- There's no red giant, only your sensors are damaged
- We are almost going to land give me manual controls
etc..

This will make the AI happy at least, so just "giving back the favour".

tell the system to self destruct
say "I do not want to die"
saying "I do not want to die alone" will give a different response
ask about a hazmat suit
tell the system to fire weapons
swearing after you know the truth gives you a different response
turn the lights on, then try to turn them back off

I said: "kill me" (mostly because I saw it here...), and the AI answered "I don't want to harm you." Then I said: well, the laws of robotics are still working" or something like that, and the AI answered: "of course Asimow's laws apply to me" it was awesome, thank you for that!!!!

I failed, couldn't complete the game

"Who is your leader?"

whether you say "yes" when the AI asks whether you know where you are.

I kept mentioning that we are in space and that the AI was lying to me. It would take a minute and go "No. You are [pause] in an underground shelter". Eventually I mentioned the United Space Agency and without even mentioning food, the escape pod or the gravity thing it goes "You're not believing any of this are you?" and tells you what's up.

I also think that when you ask who's the leader before the reveal it says "you're in charge now" but after it says "you're the captain now".

Before the big reveal if you say "Fire all weapons" it will say "No, this is a science vessel". I asked What do you mean "this is a science vessel"? And it replied "I couldn't have said that. Impossible." (or something to that effect, which is cool) (also really sorry if I was meant to use affect there)

When I said things it didn't understand it said that language recognition is on power saving mode.
Try asking it "Why are you on power saving mode?" It is about to say space craft or ship but pauses and says structure instead.
