bler144: Customarily the claimer of the prize at least briefly describes the solution ;)
For those of us too lazy to actually work it out, but who are curious nonetheless!
(p.s. Congrats on solving and getting a game you really wanted!)
park_84: It wasn't really that hard and the hints make the solution quite straightforward, by converting the numbers to binary you can get a pixel art with the actual code sketched in it ;)
Just, as an addition:
_Remove the letters, then treat everything that remains as one number per line.
_(This is the mistake I initially made) If there are not enough digits in the binary number (i.e. less than 19), add leading zeroes!!
So the numbers in decimal become:
489335
82241
223095
82964
489335
And in binary:
1110111011101110111
0010100000101000001
0110110011101110111
0010100010000010100
1110111011101110111
This way you can see the first numbers of the code: 3E252
(in case you still don't see it, attached is the code with 1's highlighted.)
Continue like this with the remaining lines.
The reward is Gobliiins
And I'd like to take this opportunity to once again thank truhlik for the great puzzle!
