Neopard ghost just teached me how to use a new secret trick on this level ! Instead of switching the gravity and loose a lot of seconds, he just go to the 2nd platform and propulse itself to the good way with the bomb : with that the laser doesn't kill him and he can get a lot of bonus time ! Wow, congrats !
We have been doing this for a while now, the first person to do this was LANTARNAX, or something like this.
