It hard like geometry dash and we like that its smooth. And can you please make more skins.
This game is really addictive and is a great challenge. This game is so much fun. We also like the different colors we get to choose.
Its really addictive but to hard and its like Paper.io now that we think about it.
We rate this game 4stars because Averyone kills us and we dont like it we were in 2nd please but still we know why thay say it is the hardest game ever EVEN thay kill us when we just jone the game.
When we played it for the first time at first we thought that it wasnt going to be so hard but it was so horrible we deleted it off our phone because it was so hard and other players had very bad names some players had bad words in there names but for us we never make a name except one time we named our player name pitbull lover but still this game is so stupid please dont let 5 year olds and younger play this.
