Also as the person in charge of SFX in the group, I found it a bit of a struggle to get the sound effects to fit the vision we had for the game. Previously I would try to find suitable music on some of the free sound effects websites. But due to taking a sound effects class this semester, I wanted to try and create some sound effects myself. I've never tried Foley myself. I'd like to give it a try this time, if time and conditions allow.
Hope everything goes well with your project!
