Spelunky is insane. People who speed run Spelunky are insane. Someone just broke the Hell speed run world record for Spelunky. Guess what: it's insane.
As someone who is a complete Spelunky noob, I just sort of sat, jaw agape, trying to comprehend what the hell I was watching.
Kotaku reader (and frequent contributor) Trjn was kind enough to give me his breakdown.
Here's a completely unnecessary breakdown of what happened during the run.
After finding a teleporter and jetpack in the first shop of the game in 1-2, d_tea robbed the store and zipped his way through the mines. In 2-2, he spotted the secret entrance to the Black Market near the start of the level and bombed his way in. He stole the Ankh from the Black Market and then made his way to the ice caves.
In the ice caves, he spent some time looking for the Moai Head which spawns on either level 3-2 or 3-3. When he didn't find it in 3-2 he went to 3-3 and immediately killed himself. He then respawned inside the Moai Head thanks to the stolen Ankh and unlocked the Hedjet.
In level 4-1, the temple, he killed the miniboss Anubis to steal his Scepter. In 4-2, he found the entrance to the City of Gold, which requires the Hedjet and Scepter to unlock.
d_tea then stole the Necronomicon from inside the City of Gold so that he could find and unlock the entrance to Hell inside Olmec's Lair (Olmec being the normal end boss). This also caused the miniboss Anubis 2 to spawn. When he fought Olmec, he quickly killed Anubis 2 with some bombs and then made a path down to the entrance to Hell by placing bombs under Olmec.
In Hell, he just played really fast. No special tricks, unless you count using ropes in Yama's Throne to make sure his jetpack didn't run out of fuel.
Okay. That makes a bit more sense.
