I will say right now I love Breedtown 2 and I can't wait to move on to Breedtown 3 after I 100% this game! Buuuut I will admit when it comes to completing all the girls, I think the rebreeding actually bogs the game down a bit when you have to do multiple things just to breed a girl again like say the Gyaru or waitress, and it especially gets annoying when you get teleported somewhere else after breeding a girl. and having to breed every girl 10 times to completion can really make the game feel like it slows to a crawl.
I understand it's probably like this so we can see the post breeding and post completion dialogue, but I really do wish every girl had the option to instantly rebreed them like how you CAN do that with say the pornstar, the Courtesan, or the secret demon. I genuinely think every girl having that mechanic, or at least lower the completion requirment, would be a HUGE breeding convenience and time saver.
But again overall I REALLY do love breedtown 2, I just think it just takes a bit too long to breed lol.
