Where exactly is the correlation between render quality, "missing renders" and "tanlines"? Anyone can clearly see that the renders here are superior to the ones in t4bbo's first game. Higher resolution, shaders, assets, lighting. It's like comparing a AAA game from 2015 with a AAA game from 2022. There's obviously an improvement in quality. Denying that would be lying.
The scenes might be the same in most cases, but they do play out differently depending on previous choices, and there ARE scenes which you only get to see if you make the right choice for it. And yes, you can't really compare the two yet as this project is barely at a point where branching would really impact it. The different paths are there, you just don't really see it as the game is still in it's baby shoes, more or less. The path for several different routes is set, t4bbo just needs to develop them further. Which I'm sure he's going to do.
The one thing I personally would really like to see an improvement on are dialogues (English translation/writing). T4bbo used to have a writer/proofreader, and you can tell that he doesn't have one at the moment. The translation is a rollercoaster ride.
