Has a bit of that gameboy advance/nintendo DS retro vgm feel to the sounds for me, which was really nice.
Really loved the flangery sound playing the chordal stuff in the background after 0:58.
I'm not sure if you know of it, but there's a free "articulation management" utility for FL Studio called BRSO ARTICULATE that might be useful for working with keyswitch heavy instruments like the Metal GTX. Haven't used it myself since I don't use FL, but have heard a lot of good things about it over the years.
Good work!
