Definitely like the minimalist aesthetic (though Mirror's Edge has always been my favorite, and this has a similar vibe going for it).
I'd look into adding a crosshair, fixing the floaty controls, and maybe looking into that music's doppler effect. Is the melee attack achieved via a raycast? I've always had better experience with melee by using a box collider as you don't have to be as precise.
Anyhow, fun little game for the jam :)
