Just finished all four characters, and here is my feedback, in decreasing order of severity.
1. Please fix multiple clients sitting in the same chair. It makes it very difficult to give them what they want if you can't even directly select an individual client. I've noticed it mostly happens on the first barstool. Is the position of the second barstool properly configured? I've also seen it happen in the chairs, but less frequently.
2. The male character is a fun change of pace! I enjoy the gay content, although I know it's not for everyone. That being said, the guy still moans like a girl during the blowjob scenes, which is a little weird. I'd prefer no voice at all to one that doesn't seem right.
3. On the topic of gay scenes, I wish there could still be female clients when playing as a female character. Lesbian stuff is fun too!
4. Some more diversity in the game would be nice. Everyone is the same skin tone right now, which feels unrealistic and a bit uncomfortable for me. Ideally, both clients and new playable characters with different skin tones would be a great improvement.
5. I didn't realize there is a trash can in the upstairs rooms until I was on my 4th day with the last character. Maybe that's just a skill issue though.
6. Another way to change the drink slot other than the scroll wheel would be nice.
7. Is there any consequence to corruption yet? I think it would be cool if it changed something other than the threshold to accept offers, even if it was just an animation change, or different expressions at the higher levels.
All in all, I thought it was a fun game, but it's definitely not finished. Looking forward to future updates. Fixing bugs I think should be a top priority, but more content would clearly be great too. Clearly you have room for a lot of new characters, so I'm excited to see what you come up with, especially for harder difficulties. I think characters with disabilities could be a fun addition to add some challenge.
