By the end of the first playthrough you'll have a pretty good idea of what it's all about. And by playing it a second time in the New Game+ mode (which is like a "part 2" of the story), it'll all get even clearer. 😉
For each challenge/puzzle there's an adaptive and progressive hint system to help you out, but I'd like to avoid posting specific spoilers here.
If you need a more walkthrough-like support, join the A.P.P. Discord and I'll gladly give it to you over there. 👍
