As I am a fan of the original BD five-level concept and as I had many ideas for caves that fit well into this concept, I started the series "Dustin's Boulder Dash".
The aim of this game is to be very close to the original BD concept. As the original BD games, this game features 16 caves and 4 intermissions on 5 difficulty levels. The levels differ only in random seed, time limit, number of needed diamonds and speed (just as in the original games).
I think level 1 has a difficulty similar to the original games BD 1 and 2, while level 5 is quite difficult (at least I have problems to play through it without a Game Over).
I also named all the caves and ints, but the names aren't given in the game (the caves are just called A, B, C and so on as in the original games).
Here are the cave names:
A- Fly Flap (remark: this cave looks harder in the screenshot than it actually is :))
C- Magic Square
M- Cash Machine
N- Magic Square II
Int4- Bad Company
Enjoy the game :)
