I'm glad you liked it. It started when I was trying to improve my melee attacks. I added the enemy-cutting effect I learned here:
But it was too fast and you couldn't even see the enemy being cut properly. Then I had the idea to zoom in on the camera and then, after cutting, suddenly slow down time and then go back (I even wanted to do this with a slow-motion sound effect, but the build web doesn't accept sound effects for some reason). Then came the idea for the ability, to Freeze Time. Draw a path with a standard Unity line; time is 90% frozen so the game doesn't stop completely. When released, it quickly follows the path, cutting all enemies along the way.
