Making a Survival Game with 1 Pixel

17.01.2023 0 By admin

I made a survival game with 1 pixel!
and Guess What

You’re looking at it right now.

I know what you’re thinking, that’s just a
black screen

BUT, in the very center there is a tiny point,
turning just the right colors, and flashing

just the right way, for there to be just enough
information to display a game.

…Unless YouTube compression has removed
that pixel, in which case you ARE looking

at a black screen.

BUT, if we zoom in, there we go, you can now
see the colors and the flashing, but you can’t

really see the game.

By the end of this video, you WILL see the

And you will know, the only way to escape
a hungry bear, is by eating blueberries and

drinking freshwater as fast as possible.


I’ll tell you why.

I’ve seen other people’s videos about making
restricted games and I like those videos,

and perhaps more importantly, I like the views
on those videos.

But beyond that, there’s the curiosity and
sense of discovery in the challenge.

How could it be done?

Can it be done?

When you have only 1 pixel, you really can’t
do much.

Go ahead, try and scale down your 4k master


The only options you do have are color, and
color changing over time.

Well, technically you have audio as well,
but relying on that would be cheap (and definitely

not something I considered myself), so it’s
my goal to make the game playable without


We’re going to be using Unity for this project,
because, number 1, I have experience with


Number 2, I don’t really have experience with
much else.

My first idea is for a top down game, with
a blocky gradient representing the terrain.

Hills with food and valleys with water.

look at that, it practically feels like we’re
in the great outdoors already.

But, that’s not what the player will see.

They can only see one color at a time with
their single pixel, so they need to observe

how the color changes to navigate.

This may seem like a terrible FOV to PC players,
but being a console gamer myself, I feel right

at home.

Because there’s no room for UI, we can’t have
a hunger or thirst bar, so the goal will be

simply to alternate, drink eat drink eat.

I’m using Unity’s color system and Perlin
noise to try and make a randomly generated

world to play in.

I was confident that with my prior experience
using Perlin noise, I could solve any issue.

But after a while of struggling with it, I
noticed it felt familiar, and I remembered

that my “prior experience” was also me struggling
with it.

So things aren’t looking good.

Getting the right amount of water to generate
is hard, and no matter the amount, there’s

always ditches that are just high enough not
to have water in them.

The entire point of the game is trusting the
gradient to lead you, and this is a lie!

How could you gradient?!

And I haven’t even decided whether the randomly
generated map will be infinite or have boundaries.

A small map would reward memorization skill,
while an infinite map would, well, uhhh…

I don’t really have a great reason for an
infinite map I guess.

At this point I’m having a major rethinking
of the game.

What if I have the map be limited by making
it take place on an island?

Now there’s a realistic boundary, and it makes
sense that you can’t drink the saltwater to


Now to make a… island…

Yeah, thinking about it, trying to make the
map randomly generated was completely unnecessary

and complicated, especially for a prototype.

So, I’ll just do it myself.

And I have.

The game is playable, and after trying it
out, I have to say…

it’s garbage.

You just stumble around blind until you hit
the objective.

That’s not what a game is.

So, back to the drawing board, way back.

I could have to scrap this whole thing.

After thinking, the map must be much smaller
to have any chance of memorizing it.

But now that it’s small, it’s too easy to
find sustenance.

So the map has to change slightly in predictable

There is only 1 obvious solution

A bear.

But not just any bear, a bear so sleepy and
fat that his slow waddling towards you is

easily predictable.

The bear tile moves 1 tile every time you
eat or drink.

And if you go to where the bear is, you lose.

That along with the food now dropping randomly
around a tree, will keep the game interesting.

And by interesting I mean broken and unplayable,
because upon testing it I have found that

the bear will move onto the objective and
prevent any way to advance, because touching

the objective is when the bear moves.

The bear’s slowness is now his greatest strength,
and his power is too great for the game to


The only way to overcome this beast would
be to allow him to move in real-time, but

his might could still be too great, for he
could be nigh unpredictable.

But I have an idea.

If the bear darkens all the tiles around him,
the player will be warned about the risk they’re


And the realistic explanation is that it’s
just the bear’s shadow.

I know shadows don’t actually surround objects,
but this is a video game.

You think doctors are studying Skyrim to find
out how cure wounds with cheese wheels?

The game is starting to be kind of fun with
the whole map visible, and to help the single

color view, I added a black flicker when the
bear moves, and a fade to red when the player


Oh, by the way, the saltwater kills you.

The reason?


I guess you can’t swim?

It is time to test its final form, and I have
made a black one pixel cutout to restrict

the screen.

Is it any good?

Well, some of the colors are confusing at
such a small scale.

So we no longer have apples, we now have,
uh… blueberries?

I also beefed up a lot of the colors, and
added a white flicker after death, to show

how many points you got.

1 from each time you drank or ate.

And yes, I would say it’s pretty good.

I mean, I wouldn’t charge 60 dollars, but,
maybe 50?

100 for the deluxe edition?

I feel that I have accomplished what I set
out to do.

But I’m not done yet, it’s time to beef it
up with audio and add some final polish.

Try to keep calm.

It is now time for the the final reveal.

You have a debilitating neck issue that keeps
your head facing down, so that you are only

able to see the ground beneath your feet.

Fortunately, a chiropractor is only a boat
ride away.

Unfortunately, a fat and sleepy bear wandered
onto your boat before you left, and now you

and the bear have shipwrecked onto a small
island, with only a blueberry bush and a small

pool of freshwater.

Survive by drinking and eating, but most importantly
by avoiding the bear.

Can you do this while only seeing the color
of the ground beneath your feet?

What do you think?

With an explanation like that, the game is
practically 100% realistic.

And with all that said and done, let us look
back now on that clip from the beginning of

this video.

Can you see the game now?
