This game's aesthetic is so nice! I really liked the art-style that was used here (stylized, yet simple). The visual feedback when shooting the gun was really nice too. Plus the music was amazing by the way.
In terms of the character controller, I felt that the player rotation could have been slightly faster considering the type of game you're going for. Maybe a slight acceleration for player rotation in relation towards how long the players holds the button would be nice? Clamp at max velocity? idk.
Overall, I really liked what I saw here and am excited to see where this game could go in the future! Great job!
