Lost Library [4][ENDED][SOLUTION INSIDE]

Hello again, I was planning for a more visually stunning puzzle, but I lost access to my trusty potato laptop, so I had to improvise.
At least I didn't lose these game keys. Solve this puzzle for a chance to win:

• Crossedland
• Werewolf Party
• Amanda the Adventurer
• Loddlenaut
• Vertical Kingdom
• No Longer Home
  and more!

As always, I will not share any hints if people are getting it, and I will share the solution when the GAs end.
Lets start off with an anti-human check!

Solution

• The anti-human measure is easy to beat on mobile, or by inspecting the page. If you pay attention you should be able to spot the one dot that actually hides a link. In cases like this I like to use this extension in order to find hidden links. Secret sniffer will also reveal the hidden link.
• The secret links to a comment where I left instructions in order to find the giveaway url code. You can experiment with the website, google, or check the about section to understand how it works. Once you follow my instructions, you will find this page.
• The line "the giveaway code is ylcrb" is hidden in said page. Sadly, the Library only allows for the use of lowercase characters. The format for the giveaway code is included in the previous hidden link: XXxxx.
• ylcrb becomes https://www.steamgifts.com/giveaway/YLcrb/.
