Interesting game! I'm still stuck on the password, but I also spent a little time on the game. I immediately turned on YAZ-Mode, because I realized that I would not be able to cope in 5 minutes. I also do not like time in quests, here I want to enjoy the environment, think calmly. And your game has something to enjoy: graphics, music. So far, the only thing you can find fault with is turning off the music or making it quieter for the "musical" riddle (when you remember and reproduce).
I will definitely come back to the game and try to get through.
Good luck =)
