This video is made as a demonstration of how incredibly far warpless can be pushed.

All splices happen at lives screens. All segments were taken from my own runs.

This could go faster in a lot of places, there's many slight optimisations that can be made regarding general movement throughout. However, there's two main places where time could be saved, both in level 2.2.

There is the "toko jump", where you hit the green ? circle and jump over, under, or between the circles of fire that spew out. This is mostly reliant on RNG and it is very rare that the fire will line up well enough for the jump to be possible at all, so I doubt that it will be seen in runs any time soon. There is also the "instant pipe entry glitch", as seen here: https://www.speedrun.com/cm/thread/ndekm. The problem is, doing it in one fluid motion without losing any time is very difficult compared to the amount of time that it saves, so this also might not be seen in runs for a while.

I'm not certain how much more time can be saved, but I feel like nowadays sub-3 isn't out of the question at all.

Very interesting project you decided to experiment with. I would wager we could see sub 3 RTA in the next couple years. You never know when a sneaky 2-second time save could be found.

@Sour they are literally the same thing segments of runs have been spliced together
