Dude i'm sorry to say this but it sucks. Now here are the few reosons why.
1. Poorly done terrain.
2. Sounds and spell completly off.Set the spell like this.
Event
A unit begins channaling an ability
Condition
Ability chanaling equal to kamekameha
Action
Play sound kamekameha
Say the sound is 3.45 seconds long, set the kamehameka to 3.45 casting time. When the sound ends the spell will fire right away making it more real.
3. You changed the story line to your liking. Like when king kai teaches him kaoken he says '' sounds cool'' I mean goku would never say that. I understand not exactly like the story but that would never happen. King Kai also could not teleport people, if he could he would of done it in the anime.
These are only a few reosons why its not very good. Put more work in it, get close to details. Some people out there may care about this. There should also 2 versions, 1 with sounds and 1 witout or set a trigger to disable all sound triggers. Some people might find it anoying. Well thats all put more work in it be patient.
