Wow I like this a lot!
I had a similar idea ages ago, but I wasn't excpecting the twist with the buttons themselves, it quickly becomes quite tricky
you said this has very few plays despite being your best writing. The dialog I've read so far is really nice, but the game itself has some annoying stuff: your character's color makes it really hard to find at first, there are both passable and impassable spaces in spots you wouldn't expect, and the noise during the ¿visions? is almost painful. Not trying to be negative, just saying if you want it to reach more people, maybe changing these would help.
I'm very happy to see a deckbuilder that does things a bit differently from the million spire-likes, specially if it looks this cool. The basic mechanisms show potential.
Can I suggest you remove the enemy? the game doesn't really need it, it just represents a couple of parameters, and would move this further away from all those "fight the baddie" deckbuilders.
