Play this map with dt, it's extremely easy, even a 240k ranked player like me can finish it.
For the ending / stream part, in order to stream fast enough, you need to learn how to jitter click with the hand you use to click.
If you won't bother to learn how to jitterclick, you can use mouse + keyboard double tapping. (The method I used for my first pass).
