I get what you mean, we have also played it tons of times and know the game is very based on how much luck you get in a run, but we kinda like it that way, after all, the main mechanic are dice, which are always totally random IRL. We tried to make it as fair as possible so a good player nearly always wins his runs (although some might be harder than others).
The higher floor you are the best dices you are gonna get, but after all, it's also a probability.
