That RNG in that nade was gold.
Was doing a run until i got the time when I found out the nade you throw at the start you can hit all the enemies and it throw me off which made the run shit but when I tried to redo it I couldn't get it to hit all of them also seems like a hard spot to hit. Seen the world record run didn't do this an wanted to share it and was wondering if its a new metta?
It could be the new meta if you found a way to do it consistently.
After lots of tries, its possible, but you have low odds, you need to aim perfectly, almost pixel perfect and timing perfect, doing this will not even make u gain time, its high risk low reward. Its probably a very bad idea trying to make this a viable way to do it. If you find a consistent way to do it, it will be maybe worth it.
Aiming at the top right of the grey window is the only spot hit it from now on because if u get that lucky RNG u could save time but don't count on it.
