The controls and gameplay are solid.
sometimes the "Next: [weapon]" text in the hud was inconsistent, it would say "Next:Shotgun" when i already had the shotgun equipped.
maybe i was using the jump pad wrong but sometimes i jumped only a little and sometimes i jumped very high on the jump pad
the shotgun and rail gun firing rate could be faster. I was mostly just using gatling gun and missiles
pressing tab to open up the menu was too slow, I think you it should just quickly change the cockpit windows into monitor screens instantly
personal preference but i'd like changing weapons on mousewheel instead
i could stack berserk, slow mode, and fortress mode all at once. not sure if thats intended
