Okay, dont really test many early versions anymore, but since its an actual game and something different I had to. And let me say, the quality of art and animations (when they are finished and not placeholders of course) are terrific.
And you got something for everything, like pixel art? You will be pleased. Like static, regular art? Yup, its there and good. You want animations? Look no further. The theme is so far mostly futa/charm based, but also the goblin scene points out to the game not being completly based on it, right? Would really like to see more male monsters on female in the future, but thats a personal thing. Also like the suggested future mimic and other (probably sexy) dungeon traps.
Now to lessen the wall of text, a few things I also liked.
Visible enemies: Great, since I prefer no random encounters.
The mentioned different themes for dungeon levels: Awesome, variety is what I like.
Brothel: Oh yes, more means to make money, hopefully different reactions based on characters sent to work there.
Possible capture mechanic: Combine pokemon with scene review and maybe even "harvest" monsters? Yup, me like.
And a few short ideas, mostly Quality of Life when playing.
Shortcuts for fighting, as in, hit 1 to pick fight, then click monster. Less mouseclicks.
A window showing what reward you actually get when finishing quest.
Possiblity to use wasd for movement.
Show the difference of equipment in equip menu, as in, new item gives +5 hp compared to old one.
Mention that game autosaves, avoid player confusion.
And last, possible bugs/weird things.
Clicking any dialogue box of the npc's text leads me to the dryad alchemy shop.
Skills menu says quit instead of back like other menus. Could be confused with quit game.
Quit game closes it instantly, and since its easy to missclick, ask if players are sure (also because of load times)
And yeah, grammar is ok but could definitely benefit from a proofreader. But overall, awesome start, hope it continues to grow a lot.
Edit: Forgot to write, the possible (future chance) of having a character captured in the dungeon for a while when losing sounds great. Would like a mention in any form of what the character did in the meantime. You know, what fun activities the character was... convinced to do. Or even art along with that.
