Hey! I just gave this a go and I think it's a very good idea, but I had a few issues that I thought I should let you know about. Most of these are just nitpicks though.
First off, the camera feels very slippery. It continues to turn even after I have stopped moving the mouse. It would be nice to see that tightened up a little.
The lighting looks good during the day, but it looks a bit wonky at night.
Another thing is the abundance of invisible walls. I understand that the map isn't done and you don't want players exploring unfinished parts of the map, but it would be nice to have some indication as to where these boundaries are.
It's also a little awkward to have to directly look at things with the camera to interact with them. I think it'd feel nicer if you could interact with things by facing Pearl in the rough direction of them.
One last thing, Since this game doesn't have a pause menu, there's no way to change settings without restarting the game.
Oh, and I encountered some bugs too.
When it comes to the sex toys you can buy in the house, the animations for using them don't really line up properly with the actual toys.
While both the Mega Melon and Thick Steak work, I'm not sure if the Tiny Melon or Slim Salmon do anything. (I only tried using them after maxing out the other two.)
If you sprint around and let go of your movement input but continue holding Shift, you'll continue to run in the last direction you were running in. You can even tap different directions while in this state to have Pearl appear to be running in the wrong direction.
Trying to run down a slope will sometimes make Pearl go airborne for a short moment. This problem is often called "Slope Bouncing" or "Slope Jittering" and it's relatively easy to fix!
The camera can sometimes feel a little jank when it's colliding with objects. I don't know exactly what's causing this, but it can be annoying at times, especially indoors.
When booting the game up, it plays the menu music at full blast for a split second before loading in the audio settings and quieting down.
When viewing pictures in your gallery, the game seems to slow down a ton when looking at high resolution photos.
That's all for the bugs! There may be more, but nothing else is coming to mind.
I don't know if you're taking suggestions, but it may be nice to have little side quests where characters commission you for photos of specific things.
These could range from easy stuff like "Take a picture of the statue in the middle of town" to hard stuff like "Take a picture of Willow having a bath from behind without being noticed."
This would be interesting, but I just thought I'd put down my two cents.
Finally, I'd like to say that I had a fun time with this and I can't wait to see how it goes from here!
BTW, sorry for the wall of text, I didn't want to leave anything out.
