There is a really nice idea here, and the art is pretty great all things considered. Would have loved some sort of sound or music, but with the limited time frame, I get it.
I had some slight issues; mostly stuff like the pilot's attack being very stiff and clunky, the overall slowless of handling the mech... With so little feedback, audio or otherwise from everything, it just ends up feeling pretty unsatisfying.
Still, the central mechanic here is neat, and I'd love to see it expanded on.
Good job!
