Tracer.io - Agari.o in Overwatch!

Run into orbs or melee players smaller than you to grow. The bigger you get, the slower you move. You can blink constantly with a very short cooldown, but this will eject a percentage of your mass. You also lose a small amount of mass passively over time. Grow as big as you can!

Credit to mitsiee who made this similar gamemode. My gamemode was developed independently starting back when hero scaling was on the PTR, but my (very bad) algorithm for finding when a player could eat an orb was not working well. I found a better example in their code at the time, and implemented something sort of similar when refining this mode for release now (it's a bit different because I forgot how they had done it, but the inspiration is there).
