Funny enough the jet has an altitude limit, but I never got around to adding one to the helicopter. I'm not sure if I'll keep the cockpit view, but it's there out of habit, especially since aside from the jet it doesn't really have any practical benefit. I'm glad the tank felt good, because the controls on the tank in particular I was nervous about. As for keys, yeah the control scheme is broken for MKB since it was very prototypey code and for the Steam Deck first and it's not something I could quickly fix.
