I finally got world record for highest floor.
I'll put a detailed explanation of way those dices as a reply so that anyone can try it.
To my knowledge the previous record was floor 56 or the beginning of phase 7 into endless mode.
I had reached floor 51 thrice and after the second I quit the game for a year out of frustration.
Coming back I played three runs, the first is the third floor 51 death. The Second broke the world record: floor 64 or late phase 8 into endless mode.

The third run came right after as a celebration to the world record however it went way further ahead than I could imagine:
Floor 91, or the beginning of phase 14, doubling the phase number, and I could have gone further, but I was too greedy and failed to see a mortal treat from an opponent, so I perished.
IT IS NOT OVER HERE, I WILL TRY TO REACH FLOOR 100, wish me luck
