Glad you like it! I recorded all the sound really quickly in the final hours of the jam, and there's actually not that much of it. The golf ball bounce is just a tongue-click pitched up in proportion to the balls' size, and the swing sound is a combination of a "HI-YAH!", a knife scraping against a spanner, and me saying "SCHWING!"
Having got the basic golf game down, I'd love to do an 18-hole version! I originally wanted to have a level select screen as well - I only dropped the idea due to time constraints (and opting to do FMV cutscenes, which both ate up the final couple of hours and made it slightly harder to offer the levels in a non-linear fashion).
