I really like the idea, I love mecha stuff so I hope you go further with it!
The flight model feels very floaty, like your thrusters don't have almost any power in them.
The guns feel nice, I like the selection and I hope you're planning on making some lock-on system.
The control scheme is weird, not really intuitive.
I see the groundworks of some really good mecha/flight game so please work on it more and I'll play it next dd!
