The Antikythera Society - Part I - A visual Adventure [Ended]

Finally Part I is ready sadly due to sickness I couldn’t work on it like I wanted. So this will be a Weekend challenge until Monday evening (European time).
*To your luck some giveaways will run 1-2 weeks longer even if you come later or need more time.

What you can expect

As you can imagine giveaways - you have to work a little if you want better ones :) -

As pointed it's a visual adventure you will find various tools and puzzles – so even if you are not a good puzzler and just want to look around you will be able to collect some stuff, even more if you are creative and have a good eye. I think I've been not unfair anywhere.
So be sure to enlarge the screenshots.

How it works

Sometimes you will find tools that can be used with objects. These will have two or three characters which will form – if used correctly – a 5 character steamgifts code: https://www.steamgifts.com/giveaway/_____/ DON'T FORGET THE 2nd -> /

Sometimes I even tell you how to enter them.
For example a Screwdriver XX + a Vent Y__YY → (Remove the screws) an open vent will appear.
But sometimes I won’t (of course these will be either at the start or the end XXYYY or YYYXX – just want to prevent some bruteforcing.)

You can also check out the Demo thread if you want an easy example.

But before it starts a big THANK YOU to the Sponsor which provided giveaways and prizes to make this possible:

The Story

It was quite a surprise when your diving partner told you he found the wreck of the long lost ship of the Antikytheran Society – a rather exclusive club of explorers, puzzlers and eccentrics and not to forget rich.
It sunk in rather ruff sea and not safe waters for diving. Good chances that nobody went for it yet, also good news as one of the eccentric founders had quite the fear of drowning most parts of the ship have an auto sealing mechanism – there should be air inside.

TL;DR: Now ready your wetsuit and aqua-lung and go to the Depths <--- ENTER HERE

Secret 1: 5 entry (ended by combining both Goos)
The Safe 💛❤️️ #3 ❤️️💛: 3 entries. 5 days remaining until the 26th
