This game is gorgeous! Absolutely the best looking and most original graphics I've seen in an RMMV game. The overworld environments look so professionally done and lush, and the range of animation for the in-battle models is stunning.
In the FAQ you say you're hoping to post a demo in 3-6 months, but I don't know if that's 3-6 months from now or from your last update or what. When do you think a demo would be available?
One thing that struck me as a little odd watching the videos - there are more elements translated directly into English than I expected. e.g. in at least one cutscene they say "masterless samurai" instead of "ronin", there are a load of techniques called "one cut" etc. where you could say "ichimonji". This game seems directed at an audience who adore Japanese culture and samurai stuff, so I think you have a lot of room to be bold and use Japanese language elements and know your audience will understand a lot of them by context (or in the case of the moves, get the hang of them). Sekiro got away with just tons and tons of Japanese language dumped straight into the English version of the game so I think you could do the same if you wanted. But it is a fine line to walk between sounding authentic and pretentious (i.e. "All according to keikaku") so I understand if you prefer it this way.
Also, uh, not to be a total weeb, but in one of the cutscenes one of the characters pronounces "daimyo" as "day-myo". It's more like "die-myo".
