There's a lot of heart put into this one. I especially like the art direction and overall story here. The idea that the character begins not actually wanting to fight is a fun twist, especially when it's combined with the fight/distract game mechanics. Really gorgeous.
As I play the game for the first time, I do find myself getting a bit lost in ways I don't believe are meant to be intentional. For example, if I encounter an enemy I'm not familiar with, I must first deal damage to see how much health it has. Also, with spells, I cannot easily tell what they are from far away unless I know to look for the color already. It would be nice if mousing over things outside of your range gave you some sort of information on the entity. When I play the game for long enough, learning item stats and distraction pairings along the way, the game is quite pleasant to play. I have no idea what your plans are with this game, but I think it can be more accessible and more easily understood by being a bit more transparent with certain unwritten rules (Health gained upon going up a ladder, enemy ranges including aggro and attack, etc.).
In addition, I managed to get an ending, but I don't really know if there are other endings. I'm guessing there's probably one based on the pacifism mechanic, but I don't know what exactly I would need to do in order to get it. I'm unsure if I have to not kill any enemies, not kill a certain amount of enemies, or simply find a way to take down the enemy at level 1 without killing it. If there are other endings, it would be nice to get a little hint of what to do upon getting this ending. If there actually isn't another ending, I'm probably looking into it a bit too deeply, haha.
That being said, what you have here at present is definitely fun. It's fun to go through the randomized floors to figure out the best course of action as the game continues. I was a bit skeptic about the randomized layouts in such a puzzle-like game, but it ended up being a really fun feature because of how many different ways there are to respond to enemies. I'm happy that I was able to play this game, and I hope that you can continue to make fun games.
