Puzzle Rush 70!
74 is rly great lol but the vid had 70 puzzles done in 5 mins whereas survival has unlimited time
naturally it was a joke, pointing out the lack of specificity in the title 'Puzzle Rush 70!':
according to the leaderboards, the all-time 5-min puzzle rush record belongs to German GM Matthias Bluebaum (@Msb2), having scored 93.
