act 1 on Vex 4 is the easiest among all the acts, excluding the challenge mode floor 1, but, people who first try to speedrun them don't really know how to cut lines, which resulted in longer time and higher risk of dying

here is some advice for beginners who wants to speedrun this Act

if you follow with the normal route you would use in your first attempt of this act, you might see a problem. no matter how hard you try, you can never get below 20 seconds, but, you can cut the first line here, its also way easier than the normal route

you can follow the normal route until the end of the zipline, then, you can just simply drop down by standing on top of the blue gravity block, and avoiding the spinning blade is way easier than you thought, you just need a few tries to learn the mechanics behind it

then, you see the second problem, this line cutting is easy, but, you can never get below 18 seconds. and here is the second line cutting comes in

you just need to drop down the zipline by pressing "down" or "S" key on your keyboard and land on between the spikes, and then follow the route from the right to drop down onto the last checkpoint, then proceed with what you do in a normal run

this method cuts 1 more seconds, but usually you will just result in a 19 second score, and its way harder than the first method

and here comes the hardest line cutting method, which is used by all top 3 speed runner in the list, including me, which resulted me in a second place with 14 seconds and 7 milliseconds

to achieve this, you need TONS of patience due to the difficulty for this bug to happen, because its mostly based off random, I personally took 4 hours to get this high score

in conclusion, if you wanted to be in top 10, try using the first method or the second, if you wanted to be in top 3, you MUST use the last one, which requires load of patience
