First it seems... Though I must admit, I didn't know how to solve 4). so I brute-forced it by entering all numbers and all letters. ;)

:) second ... but already have :)

thx

Thanks :)

Yeah! :D Thanks!

Thanks!

Thank you! :)

Thanks!

found it, didnt know the answer to 3 actualy. brute forced it :p

and i forgot to turn the anwser around, so i went from a-Z and A-Z 0-9 once for nothing :p

I had everything right, except for one thing... Didn't see that the answer was to be reversed! Silly me.
I already have the game, so I won't be entering. Thanks for the puzzle anyway though, and good luck to all!

I already have the game, but it was a fun puzzle. Thanks.

another day, another solved puzzle
Thank you very much!

Oh I have this one already, was hoping for Second Encounter =/
But thanks anyway, it was a nice puzzle!

I already have the game, but thanks for puzzle :)

Funny story: I decoded it, and then I...Forgot to flip it. Thanks!

Already have the game, but thanks for the fun puzzle.

Nice puzzle, thanks.

Solved, kinda... Don't understand 3. Dunno if I want this game either... Shooters aren't really my thing.

EDIT: Nevermind, saw the post above saying it was Base64. I didn't think about breaking down the equals signs down into binary as well. XP

Thanks for the puzzle!

took a while for me to realise 5 was morse code

Thanks for the puzzle

Damn thanks to my typo powers, i struggled 20 minutes :)

Exists in my account but thanks for the giveaway!

Cool, thank you :)

Many Thanks! Good puzzle you got there it was actually kind of an accident that I learned how to get #3 from decoding #2 but I'm guessing that's how you intended it.
