hum.. thanks for your feedbacks... this game is in the Point & click adventure style, which often has way more difficult puzzle to solve. Games such as Myst. If it's too easy, it's less rewarding. I tried to make a very good design for the Drill room past the keycode, because I knew it was a bit difficult. Some of my friends got stuck on the keycode but after a while they came back to the game and when they found the answer they really feel good ;) What do you think? I was thinking to enable "hints" in the gme if the player is stuck, to give some help, kind of "easy" mode so to speak.
