I wasn't very impressed by the game initially, especially by it;s nonsense trailer and 10$ price-tag. Now that GOG is running it at 6$ I decided to give it a try. It starts with a nice a short tutorial afterwards you're thrown in the deep. After my third death on easy mode I've reached the final boss under an hour of play. :) In addition, the game presents a progressive disclosure where various ships and goodies are unlocked based on some achievements. Highly recommended :)
