About the game:
Star Sky is a game about exploration, magic and mysteries. You take the role of a man taking a midnight walk along a starlit field. What will he encounter in the night?
Star Sky is not a game you play for hours on end. You play it once, see what there there is to discover and then play it as many times as you feel like before getting tired of it. Then hopefully you will return and finish it some other time, in order to unlock the end. The game is meant to be a relaxing and ambient experience focusing on creating a soothing atmosphere rather than intense gameplay. It is similar to an interactive poem. A poem that has several endings and allow you to explore different scenarios. It is important that you take your time and allow yourself to feel the game everytime you play it.
