Thanks! There are a ton of reused items though I can't recall a specific one from a super short hike in particular, other than the character controller. In any case, there's a list of the main reused stuffs above, if you're interested.
Ah gotcha. The jump dust, sound, and I think semi-solid platforms looked familiar... either way, it's a key part of game jams, knowing where to exert effort (and where not to lol).
