If you complete the Tawna bonus round in Sunset Vista and game over, you continue at Koala Kong on the map. If you do all the fast cycles for this and do the no death abuse setup for the 3rd floor out of bounds, you save 10-12s over the 40:07's cycles.

Important notes:

• This is not worth going for if you already are not good enough to copy the 40:07's Sunset Vista cycles. Most of the timesave in those 12s is from the cycles you get while going for the token and the fact you don't have to death abuse to skip the box cutscene.
• If you die an extra time in the levels leading up to or in Sunset Vista you will game over which kills your run immediately. Think about your consistency when going for this and whether you have exhausted other timesaves much greater than this available. EDIT: You also risk getting the Tawna bonus softlock that can happen sometimes. This is definitely not marathon or race viable lol
• This game over abuse trick to continue at the next level works in a few other levels (see https://imgur.com/a/yIgk8ib ) but Sunset Vista is the only case where it saves time due to other levels having longer bonuses and/or the 3rd token being super close to the end of the level.

If you have to death abuse extra times this will save less and less. Here is a route for what extra lives to get: https://pastebin.com/kRiBZKS7 The lives you get in the last couple levels of island 1 will vary depending on if you do the OoB in Native Fortress or not, but I have routed this out in the pastebin.

You may feel intimidated by the idea of a no death abuse OoB setup in Sunset Vista since it's precise, but the setup is actually very free. Basically just hug the invisible wall I do in the video below and it should work 100% of the time.

Note that there are more cycle tricks you can do in the climb up to the 3rd floor but it seems they don't save cycles so they don't save time.
