I LOVED agar.io as a kid and it's really sick seeing that concept be made into a survivors-like with random upgrades. The visuals look really nice and definitely evokes the feeling of old .io games, and the animation on the player and the tentacle looks so good. I don't know if this is a browser thing but the camera does jitter a lot and every now and then the player would just explode and cover the entire screen. A lot of my deaths also happen seemingly out of nowhere, either the lasers get too small when you get big enough or there's an invisible health bar I'm not aware of. Still enjoyed the game massively and I think with a little more polish, this could be really special. Good job on this!
