Good news for you:Since I love sandbox, I usually disagree woth most comments who critize that playstyle. However, here it´s clearly bad implemented: same interactions all over again, lack of any kind of hint, no way to track your progress, etc.
Fixing those things would be great, but since most people hate sandbox, the developer will probably go back to the previous VN playstyle. That´s a pity for me, but I guess it´s what most people want
The dev is really stubborn and is probably ignoring all of the feedback for changing it to a VN anyway and still continues the sandbox.
Bad news for you:
The dev is really stubborn and is probably ignoring the feedback of the remaining supporters either and continues the crappy implementation of the sandbox, too. He already did two posts "how to play", a youtube vid showing how to play, a walkthrough, added game saves. And he still did not recognize why that is actually all needed that someone can even play the game...
