Great fun


The game is really fun with smooth graphics. I would rate it 5 stars but the game needs more upgrades e.g. New abilities and when you get to higher levels your germ should grow as well. Still a really fun game.

Too many bots. Bad upgrades


First problem, at least in the free game, Chaser Bots.

The Chaser Bots latch onto your name and follow you relentlessly. Doing so, kills you, which forces you to watch adverts which is supposed to compel you to pay for the ad-free game (it doesn't). Real humans would grow bored and switch focus (Chaser Bots don't).

Second problem, in-game upgrades leave you vulnerable to attack during the upgrade screen. This could be solved by a slide-out panel which only partly covers the screen per upgrade type. Which would improve player retention.

Third problem, as noted by another reviewer is that there are no human players aside from yourself. Which makes the presence of Chaser Bots all the more annoying and player retention losing. If I were the developers I would put a "max chase time" limit of 45 seconds per chosen Chaser Bot before another one takes over. As this would make the game less irksome.
I would also put a "Chaser Bot Disinterested" flag to ON for the player if using the upgrade screen with a 45 second timeout before the Bots attack the player if the upgrade screen is left on too long.

All bots, not true .io game


I turned on airplane mode (cut the Internet) and the game is ONLY bots. After a while you start to see how they all move and you can pretty much avoid them. It got boring since I was the only strategist there.

Try it out for yourself by circling repetitively around a couple bots. They turn toward you at about the same time, don't get out of the way when being eaten by the bot next to them, and all of them end up chasing you. It's like there's no other important player but you.

Got boring after 20 minutes. NOT paying $15!!!! to remove ads either. Great idea, great design, poor poor poor execution.
