Just played for the first time, had a lot of fun. I did notice, though, that it seems like if you get lucky enough to get two moves in the same stat (any stat), it's very difficult to lose - use your +3 move as many times as you can afford, use your last move to swap that stat with the tournament stat, win. It's a cute little solo RPG that I had a lot of fun with, so maybe it's okay that with a little luck, it's relatively easy to win - but it is something that stood out to me.
(Heck, even with 2 moves in different stats and enough affection, I think you could basically guarantee victory - say, raise Wrath by +3 multiple times, switch Wrath to Gluttony, then switch Gluttony to whichever stat you actually need. As far as I can tell, the above would work, although it would cost 2 Affection to swap the stat twice.)
Had fun, do recommend, wanted to mention the above in case it's unintended! The art's great and I look forward to seeing the ranch and devil sheets!
