All of the achievements in this game are for completing levels, so I'm just gonng do my best to help you with all of them.

Before you start,

Options -> Pipeless ✔️

Changes the game from annoying flappy bird clone to typing challenge, plus it's much easier.

Now you can just go through each level typing away.
The next sections are just every poem written down, as having the actual poem up on my other monitor instead of following the super spaced out letters and words in-game helped me a lot.

(You can even pin this guide to your overlay now with modern day Steam)

The pedigree of honey
Does not concern the bee;
A clover, any time, to him
Is aristocracy.

An angel, robed in spotless white,
Bent down and kissed the sleeping Night.
Night woke to blush; the sprite was gone.
Men saw the blush and called it Dawn.

Old plant of Asia -
Mutilated vine
Holding earth's leaping sap
In every stem and shoot
That lopped off, sprouts again -
Why should you seek a plateau walled about,
Whose garden is the world?

A white mist drifts across the shrouds,
A wild moon in this wintry sky
Gleams like an angry lion's eye
Out of a mane of tawny clouds.

The muffled steersman at the wheel
Is but a shadow in the gloom; -
And in the throbbing engine-room
Leap the long rods of polished steel.

The shattered storm has left its trace
Upon this huge and heaving dome,
For the thin threads of yellow foam
Float on the waves like ravelled lace.

I met a traveller from an antique land,
Who said—“Two vast and trunkless legs of stone
Stand in the desert. . . . Near them, on the sand,
Half sunk a shattered visage lies, whose frown,

And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed;

And on the pedestal, these words appear:
My name is Ozymandias, King of Kings;
Look on my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay

Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away.”

If you're having trouble keeping a speedy pace- on every level except "La Mer," you can afford to slow down and type in a rhythm, since typing too fast and stuttering usually leads to the pigeon dive bombing straight towards the bottom of the screen at mach 10.

Another strategy is that you can also quickly tab out if you know you're getting overwhelmed, memorize the upcoming words, tab back in and mash them out to save yourself from failing.

godspeed, I wish you the best of luck.
