Very pretty pixel art! The backgrounds and even the menus are very detailed and sharp. I liked the girl's animations, and how there's unique interactions with every object. It's neat to see a variety of places and positions for the sex acts. An option to download the game and run it in a bigger window with 2x zoom will let players see your cool sprite art in all of its glory!
The sounds for sexual encounters are a nice touch, maybe there can be more variety of sounds for the other actions and some background music to tie it all together.
Instant reactions to button clicks work well for this type of game, you can get though your daily routing quickly without waiting for any menu transitions. The required relationship points should probably be lower for a demo, since there's not much else to do in a day.
Lots of potential, and already a strong display of how good the art and controls will be!
