Great idea for a game, but I don't like weird, forced humour. Why is princess screaming "REEEEE" for example? Is she browsing 4chan in middle ages? Also, why protagonist is OP like in some poor japanese isekai novel, not to mention other weeboo references? It's just annoing.
Too much grinding without purpose (and it comes for someone who love grind in games).
"Loli" characters look like midgets or weird children. Cleo setting seemed very interesting, but why making her dark elf? Appeal of drows lies in them being strong, evil women not tsundere midgets. So IMO it missuse of character.
But I truly wish you good luck with developing your game. Conqueror/rapist genre is seriously lacking in WEGs.
