you're comment section was closed so I wrote here instead. I added you because I have an idea for a concept that I think you might be interested in hearing about :3

Sonata Arctica

The only thing that comes to mind is trying to do it with Vsync on and off. It wouldn't be the first time when that setting had bearing on how the game behaved

Well, the two main things you want to keep in mind is this:
1. Always aim in such a way that all beams connect, as shown on the video, so all 3 segments of the enemies are damaged at the same time.
2. Your weapon emmits a pulse attack from time to time. You want it to hit the enemies at the end of its travel path, as it slows down and does an extra tick of damage or even a few extra ones

Ugh, uploading YouTube videos to Steam is bad. They should allow you to edit the comment
