This is a great entry. Agree with below comments re: visuals and sound design. I really like what you did visually, with the limited scope. Making the surfaces of these simple shapes shiny and glossy is a really nice touch, as well as the interactable ones that pop up when you shoot them. Those are easily destructible objects, buildings, etc in a larger scope project.
Felt like you guys recreated your own little Mechwarrior, really sweet. The movement speed, cockpit, weapons heating, jump jets, great stuff.
Like comments below, the turning could use some work. I would straight up make it even more MechWarrior like, and just have turning impact the upper torso/arms while your free aim is based on where its facing. Could get that classic strafe combat going.
