Tried making and recording a chart

My own phone kept crashing with errors, so I borrowed my family's better-performing smartphone and tried it. It had a default recording function, so I tried doing it while taking proper notes. I love White Spell so much that I tried it with sound on, and it became difficult to keep the capacity under 50MB, so I think I'll just upload the parts where damage is showing. (I've barely done any video editing, so it's taking time.) When I tried to put the full video on YouTube as a test, it said 'No video found,' and I'm not sure why.
