This is a fun little demo! The art style is pretty and I'm excited to see what awaits for the future!
My only immediate criticism is that some button prompts aren't super obvious what they do, specially in the combat segment: It took me a bit to figure out you have to click the blank squares and then the enemies to attack. It would help if they had a label or tooltip like "barehanded attack" or something.
Besides that, this seems like a fun project and wish you the best of luck! (And I'll pray for some yuri to make it into the game hehehe.)
