… nope; there was no prompt to do so, and everything about that first frame just read as a loading screen to me… still does, in fact. I waited for it to do something, and when nothing happened for ~20 minutes, I just used alt+F4 since there didn’t seem to be any UI elements to try interacting with. My mistake for… being patient and rational, I guess?
maybe add a “click to continue” or something, just to make it clear? I actually tried 3 different versions of the game, and not once did it occur to me that I might not be looking at a loading screen or that clicking randomly might do something.
Edit, heck, just changing “Thinking…” to Thinking…:” or “You (thinking):” would probably prevent others from making the same mistake.
