I watched that video when it came out and it sent me down a rabbit hole of speed running and gaming retrospectives that was so deep I now can't even sleep without my gaming videos. I don't even play games and haven't in many years but I'm so deep in the shit now even my daughter questions my watching habits wondering why I watch this stuff but don't actually play.
Ah the ole summoning salt a roo. I feel like we've all been down a similar rabbit hole. I went down one with one of his many Mike Tysons punch out videos lol
No he glitched it on purpose. classic tetris game doesn't stop. it goes forever until you lose.
however after certain level there is specific glitch that stops the game and it's up to you can choose to not do it and play forever, or get multiple chances to delay it few more levels then do it to glitch and crash the game. That's as close as you can get to "beating" the game
