Just beaten the game. I say the "puzzles" are not as fun as the first game. This feels more of shit you'll see in IQ test or something like that.
The first game might be quite basic, but the puzzle feels like escape room-ish and it's really fun to dig around, instead of segmented Q&A like this.
Latter part has similar puzzles to first game, but they feels pretty disjointed and not as satisfying.
Though the H scenes are better here, so there's improvement at least. If you enjoys the first game, paizuri, and huge breasts
(just like me) then this is something that's worth playing.
Regarding Bed 2 "alternate CG":
