This is pretty cute! Made me bring out the hololive wiki lol. Maybe I'd add a little "notes" section so that you can see what the answer is actually supposed to be but that might make it a bit too easy.

With enough time I was going to have a journal mechanic that would “persist across timelines” and keep everything you discovered in-game (everything you asked and witnessed), so long as it was a real holomember and you didn’t knock them out. With that, one would unlock everything in about 4 passes, even with no prior hololive knowledge, and on the player’s own efforts, as opposed to simply giving away the answers. Thanks for playing.
Post-jam edit: The journal/notepad mechanic is now in the game.
