Mystery's Riddle 2 - Advanced Alien School

[Adventure]

You are welcome.

But please don't give up. You have come so far and are so close to the end. But of course you must do what you want.

Btw you are aware that there are two stages 7a, aren't you? If you like, PM me what you got so far and I will help you to pass this stage. It's not so though as it looks.

Edit: I have to go now, but I will probably be back within 4 hours.

[Fern]

OH MY! Just discovered 2nd 7a!
Then I don't give up of course. I was just sooo discouraged seeing the 1st one.
You rock Adventure .

[Adventure]

Lol, I know what you mean. When I saw the first stage 7a, I thought: God, I will never be able to beat this. But then I thought it would be mean to expect from us riddlers to solve a level by beating some action game, and I know Mystery never would be mean. She isn't like Eugy.

I really have to go now. Good luck, Fern!!

[Fern]

Thank you .
Other stage is more friendly, though I sent you a PM 'cause of some

language barriers..

[Mistery]

@Adventure
Correct, I'm not Eugy

@Fern
I hope you will finish the game, you're so near
And as you see Adventure and me are here to help

EDIT:
Did you get a reply from Adventure? Otherwise you can PM me, too

[Adventure]

Yes, I PMed Fern back yesterday and she made progress.

[Mistery]

Thanks Adventure

And congrats to Fern for passing the final exam!!!

Now good luck for getting back to Earth safely!

[Fern]

Hmmm, stuck in space. Everyone said Stage 12 is tricky... I have to agree.
The source clue is

e****, I guess.

I tried to follow this instruction, but always bumped my head into the hatch...

Tried too, but saw nothing suspicious.

[Adventure]

You got the source clue correct. The following hint helped me to proceed:

Read the second line "it was....." and look at the URL

[Fern]

OMG, hehe. Really. I paid too much attention to the s********.
Thank you Adventure and Tracey!

EDIT: So close, still stuck at 19b, I really can't get it.

What t*** do I have to do?

[Mistery]

19b

hint: acronyms

[Fern]

19b

19b

hint: acronyms

Biggest overthinking of my alien schoolyears!

[Mistery]

Glad you got it

[Fern]

decode last message.

I hope I can graduate soon .
