Quoting Nintendo Life's review:
"The question everyone should be asking themselves is this: was it worth the wait?
We can answer, without hesitation, yes. NightSky is an absolutely brilliant experience. Every screen is lovingly crafted and each puzzle serves the dual purpose of pulling you forward and preparing you for the ones still to come, with one of the most well-managed learning curves we've ever seen in a physics-based puzzler." 10/10
