I assume the black screen at the end was caused by the lack of time x)
The graphics are really nice, the music is even nicer, and mixed with the narrative it creates a really nice and chill/ambient mood. I like the idea of the night-watcher as well. The only thing that was a bit boring was the gameplay part, even though there were cool animations while spreading stars or rowing in the boat, you still only had to press one button the whole game xd
All in all a really great game, i especially liked the idea of the night watcher :)
