Most of death on 2nd floor because on start i have 25 stamina, monster can hit immediately with 50 damage following on -25 or -32 stamina to recover health -_-.
Or few monsters, doesn't matter. Starting point stats can't allow yo pass even 3-5 keve km s unless player is lucky on safe room
UPD.Deaths to reach end of the floor:
Floor 1 - 1 death
Floor 2 - 97 deaths
Floor 3 - 28 deaths
For floor 3 could be much more but got lucky on 400 stamina in sum from few rooms in a row.
Btw, wrote that before realising game obtained ending. Still it would be nice to make things easier for other players.
