I agree with a lot of what people have said. I think if you are solo/duo etc then the timer should be longer. It is annoying getting a silver chest only for it to give nothing..i am loving the challenge aspect duo and solo but i do wish you could save where you are up too it seems a bit harsh when you die on the boss or the floor before.

I have not tried in a party yet but i imagine it would be a lot easier.

I also feel its a bit deflating when you beat the floor boss and you don't get a chest >.> that would be a nice addition...armor would have been nice too just special pieces from there.
