Not having a description and some screenshots makes it so that fewer players will try your game.
I almost didn't check this game because it only had that default pic to show.. lol 
I did decide to give it a try and I was surprised by how good it was. It's still your regular dungeon crawler rpg type of game, but I do like that there's at least a little background story to our girl(s). You could add some more story events while we are exploring the dungeon to keep the story flowing though. ;)
I stopped playing after I finished the first room of the mine because tbh I don't really like random encounters all that much and I thought the encounter rate was a bit too high for me.
But I think the game is well balanced from what I've seen.
The mini-bosses (and the boss) were a bit of a challenge (especially the first one I came across) but with a little bit of grinding they were easy enough to beat. Same with the regular mobs, I didn't really any trouble with anything battle-wise. Not that the battles were easy, but they weren't hard! It was good.
I have to also mention that I thought the facesets/sprites for the girls were good (they are cute!).
The potions in the chests were a heaven sent and I liked how we got nice equips from our enemies! YES!  
Overall: The thing I liked the most in this game was honestly the main character. I was sad that after two or three floors she went pretty quiet, I wanted to know more about her.
The dungeon (basement? lol) itself wasn't anything outstanding to me, maybe because in it you don't really do much more than pick up stuff from chests, enter lots of random encounters and sometimes meet some monsters in the map that will try to kill you. 
It was a fun game to play though. Good luck!

Well, I did a Let's Play for this game.

Notes

1) The editing on the portraits for the beast girls feels a bit lazy since the images still include human ears.

The mini boss fight warning could use a level recommendation or something. I did a little grinding but it's not how I like to start my game off, so I was completely unprepared for how badly they wreck you. Even using super potions did nothing because they did about that damage.

You probably should add images and some description to your game.
