I think it is impossible to not get hit by enemies? I tried to shoot my way out the first time and was overwhelmed and out gunned by enemies, so I thought maybe that isn't the right way out, second time I ran right behind the ship to try and escape without fighting but couldn't leave unless I killed enough enemies, I think a little less enemies or some way to take cover from them would help keep the challenge but make it feel winnable for the player!
cool art style and theme interpretation, nicely done :)
