Feels like it, At least for the way it ended. One moment your making a decision the next it turns into a slide show, showing you what happens and then bam it ends. Feels like it was rushed. I did however enjoy the game regardless.
I don't envy game developers, and this is a good example of one reason why.
It takes a LOT of hours to make a graphical game, so unless you have a whole team (and sometimes even if you do), it often takes years to finish. While you're working on it, the march of technological innovation just keeps right on going, and things evolve a LOT in two or three years' time. So there you are, diligently working on a great story, with great art and great game balance, etc., etc., etc... But by the time you're finished, it's just blatantly outclassed by the shiny new scenes from the game that's just starting development by some other developers (even if yours has a better story and gameplay)!
Now, at any stage in the development of your game, you can decided to switch platforms, to start using the shiny new tools that have just been developed, but then you have to go back and redo a bunch of the content you've already got, just extending the time when your game will finally be released. Also, let's face it, even with a story you love, after two or three years, you've also got some great NEW ideas that you'd love to try out, and you're just feeling a bit bored with the project. (Writing a doctoral dissertation is exactly like this, by the way.)
So what do you do? You can push yourself to keep going and hope that the strength of your story and gameplay is enough, or you can give up and abandon your game, or you can rush to get the game out. Like most developers, this one had already started the next project, so that may have contributed to his decision, but really, other than abandoning your game, I don't blame any developer for their choice when it gets to this stage. I mean, it would be great to know that your original concept was so good that it didn't need the latest and greatest game engine to be appreciated by the target audience, but let's face it, I'm pretty sure nobody in this industry is going to be remembered alongside Shakespeare in generations to come. (I could be wrong. Shakespeare was not considered "high art" in his day either.)
In this case, I'm just glad we got a great, finished game with what, to me, looks like 80-90% of the content I thought I was going to get. If you liked it, try out his new game and, hey, if you throw some money at him on Patreon, maybe he'll be able to completely finish his future projects fast enough to stay ahead of the curve.
