If you feel like you want to share your biggest fails on Geometry Dash, do tell me! Here, I'll even list a few.
91% Deadlocked after getting 3 out of 3 coins. Got them after, thankfully.
96% Psychosis (Twice!). Still haven't beat it.
89% Lunatic Doom Machine. I even talked to SrGuillester, the publisher, who motivated me to beat it.
90% Hexagon Force. Eventually beat it. I cried when I did. (;3;//)
