So far, i've made how the gaster blaster work and attack but the beam of the blaster won't kill the player which was easy to fix since i forgot to add a toggle trigger on the spikes in the beams so it can kill the player.

The blaster went very high in the video so i tone it done a bit sone you can immediately go up when the papyrus orange soul bones attack disappeared, then you can go up and dodge that attack then middle to dodge chara's knife. Very simple right?

=D
