Comments on String.io for Android

★★★★★ Sabrina Bradley · Nov 13, 2023

Very nice! Fun and I like how I can choose my controls. The ads aren't too bad.

★★★★★ Kimberlly Garcia · Feb 7, 2024

I understand bots, and sometimes they don't have brains that sometimes they hit their own tail like 😆😂 well it was easy to win but can you make it a bit harder? Cuz it's too easy it's not like to fare well in real multiplayer I'm losing, but this is easy can you make it multiplayer not bots? Cuz it's not competing any more it's just not fare competing if you don't want multiplayer make the bots a bit smart but btw LOVE THE GAME! 🎮😄

★★★★★ Sowjanya Archana · Jun 21, 2023

Overpowered concept METAJOY thanks for making this game please make new skins and new Arenas pls

★☆☆☆☆ Katie forschbach · Jun 14, 2023

It's ok but you can't win you just hit the walls and die. And too many ads, and it copied paper.io I say just to play paper.io but if you want to play a super hard game just play this.

★★☆☆☆ G Laustristica Joy Emerald D. · Sep 25, 2024

Ill give this 2 star bc it's the only game that I could play in this phone with the same mechanic but why does the wall install you its very annoying and why do the players keep spawning next to me. It's extremely difficult to play it bc on how many players spawn next to me after I just spawn pls fix this

★☆☆☆☆ Albert Jumping · Feb 13, 2024

Horrible. APP ADS. Uninstalled. Movement sucks. Not worth playing. Also, this developer is greedy and filled game with ads. Hence, APP ADS. AVOID

★☆☆☆☆ Happish_Gilly · Apr 7, 2024

Too Annoying, Too Hard, Too Buggy, Too Many People In A Sever, I Wish You Can Make Your Own Sever, Prop Sever Bro So ANNOYING
