Game looks amazing and feels great too. Nice polish with visuals and audio for the gun-play make it feel juicy and satisfying.
Performance was actually fine on my machine with only slight dips at expected moments, i.e. first time you shoot.
Graphically, only very minor critiques (that in no way detract from 5/5 the score) would be the footstep particle effect displaying above the character when walking towards the camera and perhaps the cube motif doesn't perfectly fit with the rest of the aesthetic.
Audio, like the rest of the game, was excellent.
Really great entry, well done!
