I did one for Sonic 2 (Genesis) and continued until Game Over because I felt like it. Normal runs are timed with the in-game-timer, so I optimized for that. The final death is also one second faster because apparently getting a Game Over stops the timer sooner.
The only level I found where you can die faster is Sky Chase (two seconds), but that requires level select.
I have Cbenni On steam and Twitch etc etc I could ask him if he wants to do so. (if he says he doesn't want to I have 'some' Admin power and could update it from here onward)
Oh, I havent been properly updating the OP anymore. Not sure if it really makes sense to do so either - what suggestion does LotBlind have for that, I still love these kinds of runs.
EDIT: updated the runs that ive missed. Ryan sadly removed his videos/made them private. I dont know if I should remove them yet.
You can, but because of the rings just above Sonic you can't get enough jump height to save more than 0.2-0.3 seconds or so, which isn't enough to save any in-game time. Triggering the first coconut quickly and getting hit by it are the key things anyway, and getting the monkey to throw it to the right requires too much speed.
Wolfenstein: The Old Blood - 3:01 (timing from first input you can lose time on [opening the glove box])
this is the quickest I think this can be done in, By using the secret on the first mission you can get killed about 2 minutes quicker than using the first armed guard in the regular mission.
