I don't know what happened in the last few days! 10 (TEN) ads before your first round each time you open. then an additional five after first round, two of them video you must watch! that's it! sorry, but that's completely unreasonable. the app is done, deleted, and will be forgotten. I know ads are necessary, but not 15 per round. that's insane.

Since its a pvp game the challenges came be a bit hard sometimes but it's still super fun. The controls are a bit whacked if you play with touch finger controls, I personally find the controls easier if you use a phone stylus. Game could maybe use some updates to help with lag. Also it would be super awesome if you could upload pictures on your devices to use for skins.

I absolutely love Agar.io — it’s one of those games that never gets old no matter how many times I play it. There's something so addictively fun about starting as a tiny cell and working your way up by eating others and growing bigger. The simplicity of the concept is genius, and the competitive thrill it brings is unmatched. Every match feels different, whether I’m carefully sneaking around massive cells or boldly splitting to take someone down. It’s fast-paced, chaotic, and strategic all at on
