Should load and play fine on any version of FL from v11.1.0 onwards.
The track is heavily inspired from various things, and I'm not a fan of that ultra-generic VI-IV-I chord progression I used, but whatevs.
Also, I don't know if can be considered cheating or not, but I did use and sometimes abuse of the single-cycle waveform resynthesis feature (which can allow you to use small fragments (~20 ms) of audio samples as-is — hopefully that won't get me eliminated).
There are quite a few other things that could be improved — especially the hi-hats, and I should probably add one more realistic cymbal if I can manage to find or maybe make one, but I only had so many hours for sound design (more than half the patches I used were made by me from scratch — including kick and snare drum).
Anyways, that was a lot of fun!
Edit (2017-04-03 01:20am CEST): Since there's a bunch of hours left, I figured I'd fix the volume of a synth or two. I replaced the attachment with the new version. Should be the final one.
