Warning, mild spoilers for Chapter 4 ahead so I can report issues.
First, let me say thanks for another excellent chapter. It was jam-packed with scenes! Some issues below:
At the end of Chapter 3, I happened to save on the "Thanks to all who support me" screen instead of the "Please save your game" screen. This caused a weird quirk when loading the save in 0.4 - the summary report screen doesn't show up right and that text gets overlaid on the "Thanks" screen. But you can back up and enter the summary as normal.
Then the cactuar scene - instant LOL.
There's a continuity issue early in Chapter 4 if you're not involved with Lucia. You still get the Naomi line "when did he take off his boxers?" when there's no reason for it. Also, the "very wet dream" part of a followup line doesn't make as much sense. Then there's a third line with "having just cum" which also doesn't make sense.
This is trivial, and I know it would be a pain in the ass because of variations in followup scenes, but I really wished I had a choice when car shopping. But if you have to choose between working on alternate car scenes or more scenes with the girls, I definitely vote for the girls. :)
I didn't go back and double-check it, but I'm pretty sure there was a typo of "irresistable" (should be irresistible) if you are on the Tanesha path. But overall the editing was quite good in this chapter.
