Sol dreamt of a strange world...

...full of rules and wonder...

They journeyed on until...

Sol awoke in an unfamiliar dark cave!

This seemed to alarm a mysterious knight
who ran off in a hurry.

Oof...I'm awake now, right?

Who was that knight?

...And where am I?

You're in Null Point — a faraway cave,
high up in the mountains.

AH! Luna, where'd you come from?!
I thought you were just part of my dream!

That's usually the case, yes. I was able
to follow you here using my powers...

...but I can't stay for long. I'll have to
leave and rest for a while after this.

Really...? But I still don't
remember anything about myself...
what will I do after you leave?

Don't worry, Sol...I think there's a
solution to your lost memories. Remember
the teddy bear you found earlier?

Oh yeah...I heard a voice when
I held that bear. It seemed familiar.

Exactly. I believe there are
other objects in this world that will help
you unlock memories of your past.

...And I'm sensing an object like that at
the exit of this cave. Sol, you must find it by—

Woah! Luna, what was that noise
just now?!

How can this be...?
Sol, the exit is caving in!

W-what?! What should I do??
We need to get out of here!

Hmmm...first, let's stay calm.
We still have time, just less than I thought.

You can do this, Sol — escape the cave
by using your rewriting power!

How can I do that...?

Look around you...doesn't some of this
seem familiar?

...Oh, you're right! It looks a little different, but there are objects, blocks,
and rules here like the ones in my dream.

Indeed. This cave has objects
like rocks, mushrooms, and fossils.

As for object blocks — there's a block
for mushrooms, Sol, fossils, and gold.

Yeah! There's also the connector block...

And a state block. Hmm, this one says SINK.
I don't think I know that one.

Can you tell me what it means, Luna?

Hm...remember Sol, I won't always
be here to give you the answer.

Instead, I can show you how to approach
problems that are new or unfamiliar.
That should be more useful for you.

After all, the first step to solving
a problem is to understand it.

And the more you understand a
problem, the more your rewriting
power ​grows when you WIN.

Really? Okay then, I'll try...
but where do I start?

Let's try this — make new rules with the SINK block by using these 3 object blocks.

...New rules? So I should try
making SOL IS SINK, FOSSIL IS SINK,
and GOLD IS SINK?

Yes. Each time you make a new rule, pause 
and notice what happens. That should help you understand SINK and solve this problem.

But remember, it's okay if you don't solve
the problem right away. What's important is
that you try to understand it first.

Right...I just need to try my best.
Let's do this!

What did you notice when Sol pushed the fossils into the mushrooms?

Phew, I barely made it out of those
caves in time!

I’m glad you’re safe, Sol. I know you were scared at first, but you did a great job tinkering to understand each problem.

Sadly, I have to leave soon...but before
I go, I want to make sure you understand the BOOM and WEAK state blocks.

...Alright, I'll show you what I learned!

WEAK

BOOM

SINK

WEAK

BOOM

SINK

Hmm...when the crystal is touched it
disappears, but I don’t. The crystal
must be WEAK.

Correct. When an object is WEAK, it
disappears if it touches another object.

WEAK

BOOM

SINK

WEAK

BOOM

SINK

All the fossils are disappearing at once, whether they’re on the water or not. So the fossils must be BOOM!

Correct. Making an object BOOM instantly destroys the object, along with any other objects on the same space as it.

You’ve done well, Sol.
Your rewriting power has grown...

Can you sense it? The object that will
unlock another memory...it’s nearby.

Hmm...yeah. It’s faint, but I can feel
myself drawn to it.

...This must be it! I hope this works...
I want to know who I am, or how I got here. Anything, really!

Carefully taking the diamond, Sol hears a sinister voice...

What will happen when you
are no longer YOU, Sol? Have a good,
long sleep to think about it...

Ah! It happened again!
This one had a different voice though...

And what did they even mean by that?
How can I not be “me”...?

Well, that’s sort of what’s happening
right now...I don’t know who I am.
Who is “Sol” supposed to be?

...Hold on, did someone do this to me
on purpose? And if they did...why?

I still have so many questions...
do you really have to leave, Luna?

I’m sorry, Sol. But I know you can do
this – discover the truth.

Travel this world and talk to others
along the way. Practice rewriting and
keep growing your power...

If you do, I believe that you’ll find all
your memories again.

It looks like I’m out of time here...

...But we’ll see each other again.
I believe in you, Sol.

Thank you for everything, Luna...

Okay...I can do this. I’ll try new
things and see what happens, just like
Luna taught me!

...And maybe I’ll make some
new friends along the way!

First things first though, I need
to get down this mountain...hm?

Are those...footprints in the snow?

Could they be from the knight
I saw earlier...?

There's only one way to find out.
