I'll just get my complaints out of the way: the widescreen with a giant mech taking up half the view is frustrating in terms of actually seeing what's happening, the lens flare from firing compounds the vision issue greatly, and this is the first game in the jam that my antivirus tried to destroy outright instead of just running the game in a sandbox.
Despite all of that, and roughness in animations/etc, this is a demo rivaling what entire companies might put out after months of work. The atmosphere is solid, the shooting actually worked for me once I got use to the weird angle in targeting, and the limb damage on enemy mechs looks like it came straight out of a Mechwarrior title. There's a part of me that simply cannot believe this demo was made within the time limit, and that's a good thing.
