HO-HO-HO MY DEAR STEAMGIFTERS!

*Without me by Eminem starts playing in the background*

First of all, some of you may remember me as the guy of the magic-dog-puzzles, or the guy of the video-puzzles, or some of you may not even remember me but still...here I am again, writing a discussion in my favourite community.
I know I know, I haven't been here for ages, but my last years have been quite an adventure with me divided between university, part-time jobs, nearest, dearest and the like...do you know those times when you set aside something and it bites you in the arse when you least expect it? Well that's kind of story of my life.
But I know you, you naughty guys and gals, and I'm sure you're already wondering: "Where are our GAs you melancholic chatterbox?". Hold your horses fellow steamgifters, I'm here obviously I'd say to make some welcome-back giveaways...but also to advertise something with a puzzle.

The APP

Two friends of mine developed a free, unity-based, android game: King Frog's Riddle.
KFR is a tiny riddle game you don't say? ( ͡° ͜ʖ ͡°) started just as a joke but that later became a real project. The developers are first-timers so everything is duper-low budget, really essential, and many riddles were openly inspired by other puzzle games; but still is also surprisingly engaging despite being their first "experiment".
And there are two silver linings in them being a small and newborn team: the first is that I managed to join them as their translator, and the second is that they're completely open to suggestions, corrections and anything else.

The GAs

Without further ado, let's get to the juicy stuff:
You can find the first batch of GAs by putting together the XX letter of the XX line, the XX letter of the XX line, the XX letter of the XX line, the XX letter of the XX line and the XX letter of the XX line...but many, MANY, more GAs are awaiting the ones who dare facing King Frog's Riddle and answer its puzzles...and if my memory doesn't trick me I know that you guys have a special taste for enigmas and riddles.

• The more riddles you answer, the more rewards you'll grasp, and of course, the hardest the riddle, the tastier the prize.
• Here you can download King Frog's Riddle.
• The game is so far made up of 30 riddles, that must be answered in order (when you answer riddle 1, you unlock riddle 2; when you answer riddle 2 you unlock riddle 3 and so on).
• Every 5 riddles you answer, you're gonna be able to fill one of the following ITH and snag your megalicious prize:
  Riddles 1 to 5
  Riddles 6 to 10
  Riddles 11 to 15
  Riddles 16 to 20
  Riddles 21 to 25
  Riddles 26 to 30

I won't name the prizes, but it should be enough to say that there are XX GAs, with an unbundled top XX community wishlist giveaway so, what are you waiting for my dear adventurers?

Good luck guys and happy solving!

P.S. All the GAs expire on XX the XXth
P.P.S. Maybe I'll keep posting some treats here and there

tl;dr
Missed you guys so much, I'm back to gift you some GAs (line XX), and to challenge you to solve some riddles in exchange for more (and tastier) GAs (line XX), also maybe I'll keep posting some treats here and there
