Its good but...

Even though the CPUs spawn with like 200 or less mass the game is still good, once you join and start playing they get mass from your deaths, and get bigger, but it would be better if the world was much bigger and there were bigger players for starters, and its really easy to get number 1 when you first join so, you should fix that, and also get different game-modes, like teams and so on, and skins and even an online mode, that would be fun, and also add mother cells, and add different controls like a whole screen movement control instead of a joystick, and add different levels of difficulties and so on and so forth, if you added these that would be great, it would probably get better praise than agar.io if you did.
