What a nice game so far! I first played a decent while ago (a year? Can't say) and the "current" build 5.0.1 swoops in and revamps EVERYTHAAANG. I'm really impressed - an RPG Maker Game that captivates me =)
Since I really want this project to succeed (yes, I'm aware the patreon exists - will check it out soon) -> My two cents here: I'm sure the overworld map will get some polish (details), which would be nice.
But my biggest issue with anything so far is the very tiresome - large text font. Nothing is formatted, every dialogue looks identical. Now I can't say I know how the engine handles text, but you should REALLY reserve sometime before the feature & artwork completed version and touch up EVERY dialog panel in the game. It's needlessly hard to read and devoid of personality. Even simple formatting tags like italics, bold letters and colored passages will do well. Pinky Promise
No other issues here for me - the story seems super cool, characters are varied and interesting, you get a really nice sense of presence in the world (often times, an attentive player can spot changes on the map or spots weird/revealing NPC behavior - which makes it very entertaining when you can see events coming, very immersive) and the artwork is rather nice. Especially since it comes from you?
Good Luck with this project, it already seems like a hidden gem to me in this sea of lewd games.
