So I thought about it some, and I feel like it'd create a lot of confusing/annoying to navigate intermediate versions of the translation for chapter 2 if I released it in chunks (the other chapters are also less "soft-linear" than the first one), so I think I'll just release the whole chapter at once when it's finished like I did when I worked on the dev's previous game, that way there's a single, well-defined point people can stop playing at and they don't have to worry about constantly saving, referencing/interpreting the changelog, etc.
The translation itself is going decently well. My free time has been scarce lately, but I'm experimenting with translating in a different way to try and improve productivity. We'll see in a few weeks how effective it turns out to be. Thanks for keeping up with the translation.
