I've seen this on many profiles, a achievement showcase with their name spelled in it, However. I dont want to spend my time on getting letters like "U" because they're really late in the alphabet.

I did research in the game and I found cheat codes you could use to get more levels, but remember: you have to complete the levels to get the achievements, The codes will only unlock all levels.

The picture below here is the main menu of Lyne.

To activate them, You DON'T type the codes on your keyboard, As you can see
below at the codes, they only exist out of 4 letters: L Y N E, You have to click on
the letters at the main menu in the order of the code.

The first code is NNYYLLEE, This one gives you the first pair of levels.
The second code is LYNEYNYNENYL, This will give you all levels,
but not completed. & 999/999 crystals. Also after doing these (not sure if you
have to do both) you get an achievement.

If you're lazy and need to complete the levels, check out this guide!
This is how your game looks after:



If a code doesn't work, you're probably not typing it right. Maybe ask a friend
to send you the code over Steam, so once in-game you'll see his message on
the top left/right and you won't get it wrong.
