Below post was first posted on your Reddit post, where I came to know your game. In case you don't use Reddit now, I pasted a copy here.
Initial impressions after playing for ten minutes, in comparison to Slave Maker ...
What is done good
The schedule UI is more delicate than Slave Maker. It offers clear separation between Slave and Slaver actions and provides with convenient buttons for clearing slave/slaver/both plans.
Your artworks are somewhere between coarse and fine. Though, taking into account that you are a solo developer, you've done quite well!
What is messy
Sorry for being nostalgic for Slave Maker. I prefer bonding with a well-known character to an original character. I'd like to be able to import their fan arts. One of the great features of Slave Maker is the openness that it allows you to create your own slaves! And it gives you less burden in creating corresponding game arts of activities and allows you to pay more attention to game mechanics. I can't wait to use the plethora of erotic fan arts on Pixiv! (May be offensive to the artists, though, some day you may work out some win-win strategies.)
Try adding sound effects. Intimacies without SEs are quite boring ... Many SEs are out there on the web so it won't be too difficult to put in a few efforts and reap elevated elation.
Provision of mobile version? NSFW games are safer to be played on a mobile device than in front of a desktop screen. A mobile version should be more engaging. Ren'Py support devices running the Android operating system!
The font you use is too stylish for a newcomer. I am putting more efforts in text recognition. Maybe the font can be an option to be customized.
Conclusion
Keep going on improving the game! And maybe some day I'll be passing my affection on Slave Maker to your game!
