Composition isn't bad...
...but it's obnoxiously obvious that you used FL Studio to make this. I'll give a guess to the instruments here.
- Default FL7 drums
- Sytrus saw. If I had to guess, a Hypersaw or detuned saw of some sort.
- SimSynth pluck
- Either a Sytrus guitar or the "Plucked!" synth below 3xOsc
- Organ sounds Sytrus-y, or SimSynth
Among the more seasoned producers and critics on the internet, let alone Newgrounds, FL Syndrome is a big no-no. It just sounds mediocre and lazy. Please diversify your instruments.
