I enjoyed the moon related trivia. :)
Glad you had re-mappable controls, that was the first thing I did (chose to use arrows and space) so I hope this isn't what caused my issue. I wasn't always able to sleep, and I couldn't see the pattern as to why -- this was quite frustrating because I was ready to progress through the areas pretty quickly.
Unique idea, and other than my problem above the game plays well and is pretty polished. Nice work on your first GWJ!
