Super mixed feelings on the game overall. It's grindy with occasional flashes of brilliance. I liked the sidequests and I liked how you don't directly control her actions. But overall it's a slog, incomplete, buggy, has many scenes missing, and needs another year or so in the oven. I liked the combat even if it's pretty simple with a veneer of complexity.
Difficulty overall fairly easy. This is even without the insta-kill debug spell BBQ accidentally included in 1.00.
For better or for worse it also doesn't feel like an NTR game because you're ""siblings"" and I never got the impression the MC considered her a love interest to begin with.
The walkspeed is too slow and I ended up using Mtool to speed up the entire time in town. Honestly I spent way too much time playing this and I don't even know if I like it or not.
