Awesome! Reminds me of armored core or gundam with sliding around while dodging projectiles and firing back. Also like the inclusion of an option for a wingman, a lot of mecha games I played felt a bit overwhelming and lonely since you're usually one man fighting.
I do agree with one comment though, the enemies seem a bit small and hard to hit, I also think maybe the missile launcher could do with homing onto enemies? Unless they do, I couldn't really tell. There's a lot of potential here though and I'd like to see how it turns out with more polish.
