Hello there! This project looks really cool and i'd love to help and be a part of. I am interested in working on the Custom Sound Effects that you listed. Here is a link to my most recent audio demo: https://drive.google.com/file/d/1m1YNp2HwuNOdpQe3kVDM1mZyB5yR_Lba/view?usp=shari... (PS. I can imagine the game style is very different from this but thought it would be a good example to showcase my foley/environmental sounds)
Hope to hear from you - Alex
