"Hexagon Force V2" by IIINePtunEIII - Geometry Dash [1.8]
I realized that there are a few map packs I didn't complete yet :P. Probably I'll upload some of them.
It is an old demon so I won't rate it :P. The difficulties were different when you could play only on mobile.
Music in outro: • King Dedede Theme - Drum & Bass
