Overall this game has good potential for a demo release. The content of the game, while being little, is still very interesting and the sprite animations are good too.
My advices/opinions about what can be done in future:
- Sound is a must. It should be developer's number 1 priority.
- Walking animation can be improved
- A dialogue text while having intercourse would be great
- Idle animations are being activated too early. There should be a delay like 2 or 2.5 seconds.
Overall I'd say give it a shot and play. I'll be definitely playing the full version that's for sure.
