Hello there! Thanks for trying out the game and giving an comment :3
Here's some responses to the mentioned questions:
1. It is planned to add some events after the hp reach 0. First, character will completely fainted (fall down to ground and turn to black scene). Based on the location they are at, they may be drag to the enemy hideout or wake up and find that they had sex in the unconscious state.
2. Yes, there is a childbirth scene and it has 3 variation (mammal, egg, slime). It will changed based on the latest parter. However, you don't have to raise it and there aren't anything changed after childbirth. It is a trial in that version.
