Game short
But the enemies can also see you when they are off screen
Maybe having an indicator for when you are spotted like in metal gear solid would help
you should make a discord server and also the melee is nearly usless
can there be a really cool guy (or even a girl that the protag gets attached to) who's very strong that betrays you later in the story and has a crazy story arc for a comeback in the final boss? (may or may not be mandatory)
