I did run into an issue with the combat--the buttons were purple and clickable in the first turn but as soon as I picked one, either nothing would happen (Eva battle) or the enemy would take one action (Ratpunzel, high fashion quick step) and then the buttons would all grey out and nothing more could be done, not even running away. I was initially playing on Brave browser, on both mobile and desktop, so I tried Edge browser on desktop and had the same issue.
