Just made an account on here to say that I absolutely adored the 2.0 demo!
I did experience something (keeping as spoiler-free as possible) in the final encounter of the demo where a specific attack was being used endlessly, making it extremely difficult to complete the encounter without dying. However, I wasn't able to replicate this. On reloading it returned to what I assume was the intended pattern.
Excited for what may or may not come in October!
