Cinematic. I really like the concept of having almost flashback-style minigames in the overarching storytelling being done by Ina! That's a fresh idea.
The UI didn't resize with the window, but the 3D viewports at least did, so I could see what I was doing. Having the ball immediately stop was odd at first, since I was expecting the inertia to keep it going. The Nemu section was cute, though it felt voidful (heh) without background music and possibly some interactables. Smoother transitions between the minigames and Ina's room could be good, too! With some extra time and polish, this could definitely be a cool little adventure style.
