It was in a special Brainf*ck code, then in cesar code with an ofset. What if all chars changed to +?
The original text was:
-[------->+<]>+.+[->+++++<]>+.---.-[ ---->+<]>+++.>-[--->+<]>-.-[--->+<]> ++++,++[->+++<]>+,+++++,-.+++++.[--- >+<]>-----.[++++>---<]>.--[--->+<]>- .--------------.++++++.+.+++++++++++ .+++[->+++<]>.--[--->+<]>--.[++++>-- -<]>.+[--->+<]>++.+++[->+++<]>.+++++ +++++++.+.+++[->+++<]>,--[--->+<]>-- .-[--->++<]>-.++++++++++++.+[->+++<] >++.--[--->+<]>--.-----------.[--->+ <]>---.-[--->++<]>.--[--->+<]>,---.+ +++.-[->+++<]>.--[--->+<]>--,-[--->+ +<]>--.[--->+<]>---.++.------.------ ---.++++++++++++.-----------,[------ ->+++<]>.+++++++.--.
Totally reminds me to the current LP text somehow.
But if Canonn says its not, then its not, I understand.
