A few new things I noticed in the 10 minutes I played of 0.5: You can change your walk speed inside of your home. There's a scene gallery in your home (the mirror in the top-right). There's a portal at the end of the forest just before the werewolf cave that lets you teleport back to the start of the forest.
Based on the gallery, it looks like there's about 8-9 new scenes. Seven of those are orc scenes (bj, missionary vaginal and anal, and a couple bukkake, and one analingus). One stable scene (belly riding) and I think the last is a Golden Mug scene, but I didn't follow that route so I don't know if it's new or not.
I'm attaching a save that has the gallery unlocked (for some reason the whole thing unlocked when I repeated a stable scene) but the gameplay itself is kinda borked. Enemies don't spawn in my game for some reason.
Edit: Forgot to mention, but if you watch the second orc scene in the gallery (still named Orc Scene 1), the art will get stuck to the screen.
