Stupid question but do you intend to replace some of the minor drawings that are a bit more crude like Yamato the samurai or the dark elf bandits with better images down the line or? Really enjoying the game but at times the art clash can be really jarring. Also pumpkin queen got done dirty. Not finished the game but I really hope she makes a return. Would also love to see you flesh out some of the areas like the (Japanese styled beast women area) with new characters and missions. Amazing game and one I plan to buy on steam. Great work.
Unfortunately due to the sheer size of the game, the fact it's a one person project, and the fact that this was their only game in RPGMaker which they're not fully comfortable with even after having finished the game-
While they have expressed a desire to go back and fix/polish some things, they've moved on to newer games, and have said they just wouldn't feel right going back to working in RPGMaker.
Dev makes most of their games in Ren'Py, if they could somehow transfer over this game to that engine, they'd love to do more work on it, but unless they either bite the bullet to work in an engine they don't seem to like very much, or remake the entire game in a new engine, it's unlikely that they'll be coming back to make any changes it seems. The game has been complete for almost a year, and they've almost finished their current game, with plans already made for their next one-
Unless they made a massive choice to double down on this game and release an improved version not long after having finished it, they're probably not coming back to this.
