Have you tryed my game I created. I would really love feed back
I am using Ubuntu, so I can't play, but from the video and screenshots the game has 2 problems.
There are problems with the position of the camera behind the player. The penguin model covers the left view, you can try zooming in and out while moving and aiming so that the penguin does not cover 1/3 of the screen. It is recommended to use no more than 10% of the screen for the player
Camera movement. the video shows that the camera is attached to the character, which disturbs the dynamics of the image when the character is rotated, the camera should lag slightly behind the character, this will create a stronger sense of movement. Notice how the camera moves in relation to the player in Fortnite.
The rest of the idea is very interesting, the models are smooth and memorable
