Well, I give up.
It's very unclear what you have to do, i've read comments and after lot of times of tryings things I finally got the first code.
The 3 first symbols on the white "paper" or "book" idk, doesn't look like symbole/are hard to read. I was like "weird texture" but that's all, plus textures bugs you already knew, doesn't help.
For the second codeI had some guesses wich would make sense, but nothing works, i'm totally out of ideas, I'm still not totally sure about the last number, if it's one or two numbers I need to put..
The artstyle looks good, and the hand character was funny.
