First thing I recommend is have some music for the front when you boot up the game. While the music choice will affect how much we the audience enjoy the game, not having anything makes the game feel empty. Like I am not being transported to a magical world filled with supernatural beings.
Did like the scrolls for the banner for the chapters. A very nice touch.
Also, work on the English text. Also, the part Tsunade said, ‘you helping me with all Hokage stuff’ just felt too generic. Spice it up with, ‘your job is to help organize paperwork, do errands, and if you prove yourself, secret missions.’ This can be great to show that Tsunade does treat this as a real job and can give a great tease for the future on what to expect.
Also, might want to work on the design of the MC. He looks like a cheaper version of Naruto. This is a completely new character in a magical setting. This is the chance to let the imagination really go wild. Maybe his jacket is green to show his loyalty to the leaf. Green can also represent that the character is bland/natural like the grass. Yet green also represents growth. A symbol of your character growing stronger and stronger.
You did a good job on the character Khano. His design is unique to be memorable but still fits right at home in Kohona.
Did enjoy how you gave Shizune an actual rack.
Am a bid disappointed Ebisu is a full blown pervert in this game. I enjoyed him more as a closet pervert where he would attack perverts but behind closed doors, he is just as perverted as everyone else. He could even be an interesting antagonist who gets in your way of doing naughty things. And after every engagement, you both blackmail the other into not spilling the beans on the other. Though this is not my game and assume you have a plan for Ebisu. Though, did enjoy when Kiba threw Ebisu at the women after they were caught screaming, ‘Ebisu, I choose you!’
Did not enjoy the talk with Hinata as they walked back to the Hyugga compound. She says that being a Hokage Servant is not a job everyone can do but we don’t really see anything to the contrary. No assassins, no super grueling tasks, etc.
Did feel like the game was rusing the relationships of the characters. It feels like every second, Tsunade wants to spend time with you when instead it should be the opposite. She is the Hokage surrounded constantly by village elders, clan heads, ninja missions, and who knows what else. You at the beginning are just a delivery boy.
Did like the transition where you can just click on the background to dismiss the characters on screen.
And despite what I said about the game feeling like it is rushing though the relationship, the sex scene with Tsunade was good.
