Thank you for your feedback and critique.
I really appreciate that you took the time to play the game and shared your thoughts with good intentions.
Yes, it would indeed be appropriate to add more tags. But logically, if the "non-linear" tag isn't included, it implies that the game is linear. And yes, as you pointed out, the first game didn’t turn out very well.
As for the protagonist, he does come across as a failure in this story. I don’t see that as a bad thing since this can simply be interpreted as a straightforward tale. Not everything has to be good and positive.
All the best!
