I feel obligated to say this so I apologize for stealing first comment, but the "View Game Page" has significantly more information on the game than the submission here! I'll put the most important thing though in case you miss both the in game menu option and the tutorial:
Controls:
WSAD - Move
E - Interact, Skip dialogue, Continue dialogue
Right click - Pan image
Scroll wheel - Zoom image
Left click - Interact with UI
Shift - Sprint
