Very cool! I've played diep.io plenty, so no comments on the gameplay haha, I'm familiar with the decisions made here, both the cool ones and the frustrating ones.

I did encounter a bug where out of nowhere I was jolted onto the bounds of the map (specifically the lower-left corner) and died, killed by "Unknown".

I think thse bugs in this kind of game are especially scary because you lose everything when you die, which makes you a little weary of starting again. You might get far just to randomly die for no reason. If those are ironed out, I think you've got yourself a pretty good .io game to build upon and keep evolving here!
