Geometry Dash Blackout is challenging all players in the world. There aren't spikes, but one strong hit can break your square immediately. Good luck!
If you can see the colorful background in Geometry Dash Demon Park, Geometry Dash xStep V2 Rebirth, or fnf mods, you will surprise with the background of this Geometry Dash version. It is full of black. Moreover, you won't face sharp spikes. It doesn't mean your character can't be broken. It is easily destroyed by strong collisions. Falling down the space also can make you end the game.
