when switching to and from spacesuit sometimes sounds like footsteps, doors, etc. disappear, reloading a save file helps. maybe it has to do something with air pressure, i'm not sure.
horror is a reason, but removing a viewport on the bridge is kind of too much imo. it's a space game, a sci-fi game set in space on a spaceship, not in a lifepod. maybe a blast shield when alarm goes off or in case of events to balance it out? or what if its like on an alien ship, viewport appears when the bridge console is on and pilot is in the seat? if player being able to observe the destination is a problem, implementing a hyperdrive somehow might be worth considering too.
