7 Days, 7 Scenes. No surprise that plot is very shallow and uninteresting. One time where the dialogue is intermixed with roman japanese, like literally typing "Yoroshiku". One scene that's psuedo-ntr but it was made clear that it was the protagonist's fantasies.
CGs are a bit of a medium Tier, animated to make it feel like its "alive" like its one of those anime wallpapers from Wallpaper Engine. Sprites are boring, your usual joint animated body, the hands are a good indication.
Not a lot of voice acting in this, minor 1 liners
Conclusion: Give it a go, don't expect a masterpiece, just pure jerk of material to burn through.
