You really integrated the step countdown mechanic into every aspect of the game, that's so cool! It's super impressive that you managed to build both a full dungeon crawler and a turn-based battle system.
During my playthrough, I found that it was actually more worthwhile to spend my steps navigating around the enemies instead of fighting them, since combat usually spent steps much more quickly. I did end up getting stuck on floor one already, I defeated all the enemies on the first floor and found a key part, but I couldn't quite figure out how to open the "x2" door and unfortunately ran out of steps there.
Though, I really enjoyed my time with it. Great job
