I guess there's nothing more after you kill the two mechs? Not that there's not already quite enough in the context.
I enjoyed the game, I'm always in for a turn-based shooter, and this one is competent, "Stuck" mid air bullets are cool, the game looks good and plays nice, the dithering in both the intro and in the sky is pretty gorgeous, I grinded a bit and cheesed a lot, a satisfying moment.
