my second look:
Music:
Music was a bit too loud, good music choice tho, you should make it dynamic since it's an action game, make the music more louder when time progress/kill streak and dilute the sound if the player got hit to really sell the effect of hitting.
Sfx:
Try to change the pitch of every repetitive sound like shooting / hit sounds / Walking sfx
walking sfx is not important but it really implies that player is in the game area, not hearing it is a bit weird for me or maybe the music was just too loud.
Graphics:
I love the artstyle you went, some areas are dark and some areas are too bright, I think you already know how color theory works since the color choice was good, it's just too much colors make me loose of sight of the enemies.
there should be some color code or maybe high contrast between enemies and display light.
Gameplay:
It's pretty standard no complaints not too good and not too bad which is good sign of a good game by the way.
I don't know why but doors are taking delays to open, and one more thing dialogue should always be skippable even tutorials.
Overall:
Good Gameplay, Audio need fixing a bit proper balance and it's a great game, Graphics are bangers just try to differentiate and make a huge contrast between Enemies and Environment Design.
Good Job on the submission! 💪
