You shouldn't be hyped really, NightSky is the game in which I learned how to use physics, and my development time on it from my side was shorter than e.g. Knytt Stories and Saira. People who try the game tend to like it a lot though when they get into it.
But hey, there'll be many, many more games from me. There'll be ups and there'll be downs, you'll probably love some of them and hate others. Give it a few years and who knows if you'll see a new Within a Deep Forest game, or another Knytt Stories, or basically any iteration of the type of game I do that you like more. And there's of course also many other awesome game developers who does things you should play if I'm in a period where I design games you aren't into!
