You're welcome! I like the game btw, do like a slower pace to the transformation, though I think there could be more texts for different stages at each limbs.(just a personal preference of mine, so don't let that influence any decisions of your own)
But I do agree, the progression is going to be a bit touch and go. Just means I have to get good enough to get past floors 10-11. May I suggest something like a spell that tells you roughly where the stairs is and how far relative to you? Probably make it pricy to discourage spamming. Also, the map might need a bit of a touch up. At least a distinction between walls and unexplored tiles. Also depending on how the map expands part of it aren't displayable. If any of those issues are already brought up then my apologies for bringing it up.
I have no idea what the blue spaces on the map represent though. Seems like nothing to me.
Other than that, I'd be happy to provide some ideas of my own, like more texts for different stages of the transformation, as well as any potential mechanical changes because of that.
