That's shame on the game, really
Nevertheless, the fact that you have 32 hp, tells that you wasted too much chance to improve your deck (and the shitty dices on the pic prove that)
In 10 floors I received almost only "heal"/"remove-die" options, no "upgrade" option, and the "new dice" below floor 10 you receive only weak dice. I learned later, the best option is to restart if you don't get many upgrade options until room 10.
That's exactly what I suspected, the game only allows few strategies. For example, it's impossible to win the game just by choosing/receive new dice and heal, without upgrades or removing dice.
I managed to finish the game with some regularity, but always following a strict strategy, which doesn't allow much improvisation and rely a lot on luck on receive upgrades and really useful new dice:
- deck size 8 or 9
- start upgrade 2 attacks to max
- then upgrade 2 defense and 2 boost while trying remove 1 boost and 1 attack
- restart if you dont have 2 attacks max when reach floor 8
- new dice only after floor 10 (remove old dice after receive a good one)
- heal only if no better option
edit: I loved that game played 20+ hours, but the situations like the first screenshot are really frustating
