This is very cool, one of the top concepts I played so far! I liked how I had to backtrack and find sheep hidden in plain sight.
Two suggestions:
- Enable Fullscreen mode on the game's page (you can do this during rating)
- If Space is used to advance dialog, make it also hit Snooze, or make Click also advance the dialog, but having to click then Space and only then WASD is a bit tedious. Mouse is not needed for the game, so default Snooze to Space would be a quick fix.
Overall, awesome job!
