I agree in part. I think there are ways to properly handle timeskips. Shorter timeskips work best for me and I think every timeskip should have sufficient exposition before and after to make the context clear. The timeskip we are talking about was kinda empty. If the MC had learned something or if hed did something of note to be explored later, the timeskip would feel far better.
That said, the demos sure very nice and the art is incredible.
