1 - The Gameplay is decent, movement is quick & responsive
2 - The Topic was respected pretty well, with the art style, but the theme not so much
3 - This is pretty original in a way by having to move in the wall to get the pickups, but it's core Gameplay is repeated in a lot of other games
4 - The Lighting is pretty good, graphics overall is decent
5 - Missing Music and SFX, is a big down, it can lead to some pretty boring moments when you are playing with friends for example, adding it will help your game a lot
6 - Finally, Polish, nothing to say really apart from the Music and SFX part, adding them will help your feel more polish and finished
keep working on it, you can always make it better, gl
