Some notes/suggestions:
1. As a top, MC can't have novice guard and submissive merchant scenes if cocky guard doesn't like him, and that's not gonna happen unless MC submits to him. So another way to raise his like bar is needed, or make the scenes independent, we don't need his approval to interact with the merchant, plus he said "Seems like we are both in need of some bitch" and MC found the young lad why not share just like novice guard as *friends* ?
2. As a vers, MC should be able to choose his role if experienced enough, with the same content without breaking the game mechanics.
3. As a female, MC can't have normal service with bartender which should be normal since he's not completely gay.
I played the game a lot so it's only fair to tell my opinion, I'm personally not a fan of lizardmen not just in the game but in general even in anime, but what I'm excited about is orcs, especially knowing that Zoroj loves them too.
