Tried the demo, I like what I'm seeing so far.
And I do have some feedback.
The setting saving after you close the game and mouse sensitivity options seem the most important.
In the bar mini game the timers for orders felt a little fast, even when i got better at the mini game where i didn't miss any tables. So a little more time (maybe like a second or 2) and I think it'll feel good.
The running animation for (I'll just use the default name here) Sapphire looked a little stiff to me. It's not too bad, but enough where I noticed.
I figure this is a given, more customization options.
And for a total nit pick, I noticed some clipping on Sapphire's ripped outfit and on her tail while standing still. Along with the transparency on her new ripped pants being off.
Not really that important, but it still bothers me a little so I wanted to mention it anyway.
The climax bar diapered for me a couple times, I pretty sure after I loaded a save. It fixed itself when I exited and re-lanced the game.
I really liked the animations, and Sapphire's expressions. They were great. Though I do wish I could also hide the guy's clothes.
In total I'm looking forward to this game's future developments and when you release it on Steam. And I wish you luck man.
