A rare low-tech challenge, requiring mainly manual labor.
The given image contains lines of symbols. I converted these to characters semi-arbitrarily and got:```52M011V0i12?1J14244E102514O51J12PMOMN?7P32P4E7012P14E1437P12F50?1F7MNOMN07F1FJ4752M4E1J2P14370OX107?4E10251?7OMOM4EO037PFX3E1P1Y1P4E1P1O0FONE44E1P12P12F070E2X730?F2NO0E73F7MNXOXO442V1J7?4707FY1O4```(The question marks represent rare symbols I was too lazy to convert...)
Counting these, we can see this is a substitution cypher. "1" (appearing 30 times) and "4" (19 times) being the most frequent symbols, while other symbols are rarer.
Breaking the substitution cipher we get:```MANSEEkSpEAcEYETATTHESAMETIMEYEARNINGfORWARTHOSEARETHETWOREALMSbELONGINGSOLELYTOMANTHEYARETWOSIDESOfTHESAMEcOININTHISWORLDWHEREvERTHEREISLIGHTTHEREAREALSOSHADOWSfLAGISHOWLONGDIDITTAkEYOuTOSOLvEIT```Flag is SBCTF{howlongdidittakeyoutosolveit}
