Hello XpBarq. Thank you for the feedback!! I didn't knew about AudioStreamRandomizer. I'll for sure use it. Thank you for letting me know! I'm using godot 4.3 btw. Hopefully it is supported. But otherwise I'll try to find a solution for the sounds.
I totally get what you say about the "nothing overwhelmingly standout". I'll be working to define the visual identity of the game, and adding all that you pointed out. Patricle effects, sounds, animation for when pushing against walls. I agree 100%.
