Day 08: The Game

Description

Let’s play another little game this year. Once again, as every year, I promise it is hardly obfuscated.

perl -Mre=eval -MO=Deparse dec8.txt > dec8_deparse.pl

makes it a bit more readable.

We can run the code in perl, and see it is a tetris game

  
$ sudo apt install libterm-readkey-perl
$ perl dec8.txt

There is a flag in there that leads to a Rick roll youtube video, hmm..

We can fiddle with the code a bit to make it easier to play (slower drops, and we make all shapes squares, dec8_tidy.pl

The letter that drop do not follow exactly the rick roll video link,

but this other link it gives also doesnt lead anywhere, hmm, did we emss with some setting that affect the outcome?
