Yeh Some people seemed to struggle with the puzzle whilst others didn't, and it was something I was worried about however I couldn't really think of any other puzzles where the hint 1+1=11 would work whilst without becoming trivial and it being something to do with the number 10. I guess in a sense the target audience is programmerish since most people in gamejams end up being programmers but after the first puzzle the programmeriness of the first puzzle isn't really there
