This is trance (electronic) by the way, so please recategorize that.
For the intro, either make the snare louder, or don't bring it at all. Less Nexus presets (try Serum!), a little of high-pass EQ, less detune, make the main lead have a higher part (copy and paste it one octave higher) and add a gritty, loud(fat), side-chained bass synth halfway through the chorus. There is a bass, but it's too weak!
Also, don't ask people to use this in Geometry Dash! People will use it if they want, don't ask them to give you attention. Fix your tags as well. Second of all, barely anyone will use an 8-minute track in a level.
Rating: Decent, needs improvement.
