Everything else feels solid, so I'll only complain about controls a little: it's better to inverse either none or both default look axes - othervise it feels confusing, when one is inverted (y/pitch in this case) and the other is not; A/D definitely feels better suited for yaw rotation, then Q/E - you simply use roll not as often, as well as most people are used to having their hand on WASD most of the time.
It still feels very fun anyway, good job)
