Promising start, although not an impressive demo.
As a fan of your previous game "The Boba Teashop" I expected something more sinister, vile. The game does offer neat visuals, atmosphere, chill environment and very dedicated boss. I assume something is off about him, rather than Mari, the main character, but nothing reveled itself. Somehow, the game lacked the spices (no pun intended). Still looking forward to the full game.
Best of luck!
