A pregnancy system is not planned. That doesn't mean there will be no pregnancy, but it will not be a involved system.
The battle deadlock was a bug that has been resolved. The battles should have ended after Aylia falls. Right now it results in a game over because that system has not been finalized, but it will not be game over in future versions. Battle H will occur against certain enemies and will involve the enemies exploiting Aylia's outfit in ways unique to that outfit. For example, the peasant dress she gets will be the first outfit that is exploitable by the enemy pulling it down. She will then be susceptible to bust-attacks. This will allow me to create different battle h depending on the outfit worn in order to avoid the system becoming stale over time like in many other games (where you've seen the attacks 100 times). When you get a new outfit, it should be pretty exciting!
