This game is... particular, I can see the appeal, but I just find it funny to kill monsters and tactically getting an advantage on them. Yes, I became friend with some orcs who didn't wanna die, but mostly I've killed theme and, I mean, why I shouldn't? They killed countless adventurerers before me so why should I feel guilty? Also I find the pretense to "decolonise rpg" stupid, since rpg aren't a product of the colonial era or mindset, all your just saying is that it has a japanese setting, which for me it's a big plus since I'm tired of playing medieval europe, but stop trying to paint it as a battle against whomever, I just want to play rpg and not to think about politics, it's just escapism and I like it that way. Overall if you're looking for non conventional dungeon crawl with a strange japanese inspired setting I recommand it.
If you just want to play an RPG and not think about politics, there are plenty of other options out there. It's quite telling that you decided to comment on this one in particular just to rant about how "stupid" decolonised rpgs are. You also write about how you purposely went against the game mechanics to kill monsters, which again, there are other games you can do this in.
I think this is a marvelous little game and deserves more visibility just for trying something new and different.
