I finally got around to the update. It was a massive improvement from the heaven and hell prologue. The weebspeak is gone, the writing is better (but still typo-ridden), much fewer sprite animations for main characters even though it was heavily PoV focused, much more natural and varied movements in the animations, the masks were all seamlessly done, and the previews for what's to come look even better. I didn't like how much dumber the protagonist is in this iteration, though... He's much more slow on the uptake as to the dynamics of the world than he was in the previous iteration. Being in a hospital bed isn't a good excuse for that, IMO.
My main worry at this point is why Snats is still so bad at Ren'Py scripting. If what he's said about the delays is to be believed, he's having a hard time with the variables for the sandbox mode. There are basic techniques you can use such as nesting and conditional loops in addition to if/else statements and label jumps to differentiate game states for a sandbox/free roam stage that don't get into any complex techniques or coding with more complex things like classes, lists, or objects. You can also comment your variables using # in Ren'Py and use a GREP style search program to keep track of comments without being overwhelmed.
Hopefully he learns some processes to facilitate the scripting process for him or he'll end up being perpetually overwhelmed, if that's what's holding him back and not the writing or rendering process. He's always been on the faster end for rendering, so I really doubt it's anything to do with that. His writing isn't that complicated, either. If I were him I'd set some time aside from other aspects of the development process and focus on learning techniques to facilitate and streamline scripting and debugging to avoid getting into situations where those become a bottleneck in the future.
