That's a very extensive cave system for something made in two weekends, which I think made scope grow way too much, especially since it seems you also did your own music. Cutting the size in half and spending more time on rounding out the experience would likely be more satisfying both for you and the players - even at the price of having to put a "This is a dead end, couldn't make more" sign after a few rooms (like I did :p).
You got a lot done in a tiny amount of time, kudos for that :).
