Plus some where she had a bit of help from chat, and a couple where she made her own references.
I'm pretty sure I got all the ones that she understood/talked about, but if I missed any, lemme know in the comments. Also, if you wanna know the timestamps in the original stream for any of the scenes here, just ask. I've got timestamps for DAYS.

Disclaimer: The desk slap counter is only representative of this video, and does not represent the total amount of times Korone slapped her desk in her full playthrough.

The full stream is seriously a blast to watch, even without subtitles! Check it out!
