The idea I had going in was it was going to be a strategy game based on preset dice rolls(Which you are able to see 6x in advance). You use the die to attack the enemy uses the same rolls. I had planned on more things to use the dice to give you the option to shuffle through them more to make things more strategic. The only other big thing that I manged to add was fate/curse which lets you use points to crit or fail any roll.
I ended up spending most of my time getting dungeon generation to work correctly*.
