First Contact players have expressed their desire for a hint system, just in case they'll encounter a puzzle that is a bit difficult to solve. We are working on a hint system and deliver it as part of the game as soon as possible. In the meantime, if you are experiencing difficulty in solving some of the puzzles, please use the game forum and ask a question, or email us at contact@eis-interactive.com. We encourage players to express their thoughts about the game so don't hesitate to reach out to us. Eis Interactive Team
