I'm glad to hear that my feedback was useful for you. I can't do much to help you about the VFX as I'm not into this area, but I'm a composer and I've made some nice ambience music. With some more discussion and proximity, I could make you just the thing you're looking for. Your game has a lot of potential, mainly considering the future features you mentioned now.
In case you want to talk more with me and you have a Discord, my nick is @caquittoplasma22
I could show you some of my music as well :D
