I love commenters on itch.io... you saved my ass with deciphering all of this <3. This is just so people who struggle with trying to decipher this on their own (like me), have it in one comment:
- Level 1 uses Shift Cipher (I used dcode.fr site, because it shows different variations for the answer) like @PYOPYUN.co said,
- Level 2 uses ROT47 (I used browserling.com) like @apollochoco said,
- Level 3 uses Binary Code (I used binarytotext.net), which gives us once again Shift Cipher (back to dcode.fr)
All that said... the deciphered cheat sheet... is very interesting (⚆-⚆). I can't wait to see more what the creator cooks for us <3 (cuz Kane is already yummy, lol)
