If this one can keep up the momentum and actually become a fully fleshed out game in the future, it has all the makings of a gem. Keen artwork, unique sense of style, map exploration. It definitely has a flavor of all of its own.
I do agree the voice acting can be a touch cringeworthy here and there, but that is often the case with games. It also may be due to sound effects in the rest of the game are few and far between, leading the moments where they speak to be especially jarring.
Any plans for adding party members packing a little extra downstairs eventually? (Futa, shemales, traps, etc.) Asking for a.. friend. Right.
Nothing wrong with a duo/trio/whatever of heroines misadventuring about, mind. Finding a party style rpg done well in that regard is few and far between as is.
Best of luck in the future!
