Wow, I'm really enjoying diep.io, and I just realized it's extremely similar to the game in this post. The OP must have seen diep.io and borrowed a lot of game mechanics. But they still didn't do it right, because I only played their game for a few minutes, while I was hooked on yours. That's a very valuable lesson: the game has to be fun and engaging, and the technical details are almost insignificant compared to that.
