Hehe, you're not escaping a thorough review!!!
The intro was perfect, but I feel it should have completely kicked off after 8 bars instead of the 12.
The synths are really good, and the filter effects are good too.
From :42 to :52, it feels a little empty with one instrument controlling all of the melody. The addition of high hats alleviates that feeling a little bit after :52, but it still feels a little empty.
That sliding synth that comes in at 1:05 is sick. The melody and it's sound, everything about that synth is nice.
That rapid-hit synth that starts fading in at 1:18 just doesn't feel like it belongs.
At 1:44 when it hits that lull, I like that section alot. Piano sounds good.
Immediately after that section: great choice of synth and melody.
That sonic-sounding section and the high-pass fade in: Great.
The highpass fade out: bad choice. Makes it an abrupt ending in my opinion.
Overall, 9/10. Good work and keep it up kid.
And to solve your synth problem, I would have just replaced it with a synth similar to it, or just remembered the knobs and completely started the synth over. You lost so much of your song just because of that damn synth, that's not good.
