I actually play real geometry dash but I kinda have skill issue so my hardest is only a hard demon. Any key works as input. (well, at least the keys that scratch accepts.) Complete with hitboxes that are accurate to the real geometry dash experience! (in other words, they suck.)
A silly project made in 5 minutes. You should comment "Glorbfub" if you are a true geometry dash fan and saw the thing. <salute_emoji> EPILEPSY WARNING
