Looking at the newest release that's coming out. I'm so at awe at how much you and your team have improved since v0.1.2, the version I first played. Every update keeps improving upon the other. It's deadass kinda inspiring. I can't wait to see what the story is about. A very rich and well developed story that shows the characters, backstories, and hobbies would really be amazing and add to the already great art style. I at least hope the story would be finalized and completely thought out before implementing it into the game. Something I think would be nice but optional is, customization? Able to customize only the first 4 girls or just leave them as they are. Like hair and eye color, length of hair, breast, butt, and thigh sizes. Maybe even extend to the protagonist, like dick size. It could be a lock option, so no changes could be done afterwards apart from the clothes they wear. I did see in an older comment about a stat drain and found that interesting. I know it would likely mean more work to make different models but it could a cool optional feature if done right.
Also, no!! Takahashi's work uniform is gonna change!! (o・`Д´・o)
