For a movement prototype I don't dislike this at all.
Some notes:
I started the game and the camera pointed straight down at my body and it very disorienting, took me a while to realize what was happening.
Cockpit UI limits visibility too much, I assume it will be complemented by the radar once it's working but also maybe smaller frames could have heads that give more visibility.
With the autocannons at point blank I was having trouble hitting the target's chest, I think the arms are covering the chest hitbox.
Boosting when the meter is at 0 stops your mech which seems unintended.
Boosting is also very sluggish. Fine if you want your mechs to feel heavy and sluggish but if you want to make them feel nimbler then boost should give you around 10 times the acceleration it gives right now if not more, just to help you change direction or correct your mid-air movement better.
