Now, before I go off on how much I love this game, let me at least try to show a semblance of fairness by touching on the singular aspect I dislilked.
Spoilers ahead. You have been warned.
Part 2, arising after you defeat Leshy and begin a new game, introduces a variety of new cards, mechanics, and locations to the game. In fact, it opens up the "original" world of Inscryption, with a host of new characters, several small new plot lines, and loads of intruige, for those clever enough to parse it out in between balancing their new deck and the piles of cards and mechanics they will be inundated with.
And, in truth, while Part 2 is a little clunky in its execution, the puzzle elements, the story, and the curious ominous feeling that accompanies even your supposedly triumphant and hopeful arrival to "how Inscryption was meant to be"; once you get over the learning curve of the new cards, there appears to be a revolutionary choice in front of you.
And here is where we run into my only true gripe.
The end of Part 2, and the inevitability of Part 3.
If you're still reading and didn't listen to my earlier spoiler warning? Last chance. This is where the spoiler sauce is applied *generously*.
P-03, the rotten robotic scoundrel, decides to imitate Leshy, and take over and remake Inscryption in his own image. Which, if you didn't love his deck styles? Too bad, because now that's all you have, for the majority of the rest of the base game.
But that's not my complaint. It's not even the inevitable ending, as it arises. That, in fact, I found touching, moving, and it even made me cry just a little for the fate of this beautiful world, to watch it end due to the monopolizing greed of one Sage.
My complaint? That you cannot go back and experience what the world of Inscryption would be like had it been taken over by the other two Sages (barring a brief fight at the end.)
Other than that? Phenomenal! And, as you may learn: the true game starts after the end. ;)
