anyone wants to play a new diep.io clone (multiplayer online browser game with no registration)
https://havre.iosadly it lacks activity making it more like single-player, but that allows you to level up and score in peace for practice, then spin in a corner waiting for more to show up.
Controls:
WASD - move
Mouse - aim
E - auto-fire
C - spin
a concentration of large geometrical shapes and power-ups can be found in the center, in diep.io there would be competition for it.
