OK. This isn't the worst geometry dash clone, but it isn't the best either. Firstly, the jump is too high and it lags a bit. There is no customisation for characters and there is no level editor. The levels are like the original game, which is ok, but then you might get sued by the creator because its almost like the original game. The main menu is one of the worst ive seen in ages and its plain ugly. This is how you can improve it:
* creative levels,
* character customisation and level editor,
* improved main menu,
* less lag,
* and finally, lower jump.
I hope this comment helps. Try and improve and maybe i'll leave a like. Thanks!
Yours,
Daniel :)
