Insanely impressive! The locomotion is excellent and truly anime-mech-like, the visual style is superbly polished for a jam game, the particles beams and explosions in particular are gorgeous. My favorite has gotta be the trails on the missiles. The 3D and 2D art across the project is really awesome, those are some great character designs.
my only feedback would be pretty minor stuff-- the city could use some greenery, skybox is a bit bland, missions don't really tell you where to go afaik (I just fly up high till I can see the objective). I also had a bugged mission where I cleared 5/9 waves, it even said 0 enemies remaining, but no more would spawn. Also for me personally the camera tilt when you move side-to-side is too much, motion-sickness territory. But these are all minor nitpicks on what is an excellently executed project, very impressive for a team of 3.
