Hi, this is a cool story, but it really needs to understand more variations of answers.
For example, here's a snippet from me playing:
Do you...
Stay in the capsule of goop. You want to know more.
Jump out of the capsule. How do you know this 'thing' is telling the truth?
> stay
What do you decide?
> stay in the capsule
What do you decide?
> help
What do you decide?
> stay
What do you decide?
> stay in
What do you decide?
I could only continue because I looked at the source code.
In some other cases I could guess the answer I wanted ("desert", "climb") but not always. For example:
What do you do?
Bite the creature's hand so it lets go, then run away.
Bite the creature's hand so it lets go, then scratch its eyeballs.
Do nothing and surrender to the creature.
> bite then scratch
The creature is angry and time is running out... what do you do?
> bite
The creature is angry and time is running out... what do you do?
> bite the creature's hand
The creature is angry and time is running out... what do you do?
> bite the creature's hand so it lets go
The creature is angry and time is running out... what do you do?
> bite the creature's hand so it lets go, then run away
The creature is angry and time is running out... what do you do?
Another case is where the text says I can "Stand motionless" but the actual command that works is "don't move".

In my opinion, the best way to fix these kind of issues is just to watch someone else play your game. If you are careful to not give them any hints or tips, then watching them will quickly reveal where you need to make tweaks to the game easier to play.
(I also made a text adventure for this Ludum Dare, and I was lucky enough to be able to watch some friends play my game, so I could change a lot of commands to ones that they found easier to understand.)
