Yeah, that's been a definite theme in the responses so far - in hindsight I probably should have found a way to cut the wait down, but in previous jams I've often ended up spending too long tweaking details early on. This time around I pretty much spent the Friday evening of Global Game Jam working out the golf mechanic, the Saturday making the levels, and the time left on Sunday doing all the effects, sound and video (though the video took long enough that it only made it into the GDevelop Jam version, which had a later deadline).
