All the puzzles (password and pictures of Lisa and Alice) aren't difficult to solve. You just need a bit of patience. So far, I've solved Lisa's picture 13 times and Alice's five times. I have to do it again with each fix because I play through the entire game after each fix. It takes me about three hours to complete the entire game. Alice's picture didn't appear until the second part of the update, so I only did it five times, for v0.07.70, v0.07.71, v0.07.72, and v0.07.73 twice (two paths). Since v0.09 is still missing in the first chapter, I'll have to do it a few more times (depending on the number of fixes).
