But from my own previous experience with coding: longer pauses between updates equals more wasted time. Procrastination sucks.
Don't mean to harp on this like everyone else, but what kind of coding did you do to get an impression like this?
Because in general this is hardly true. Coding is unpredictable, bugs can take a days to solve or 5 minutes just depending on how quick you happen to find the right cause of it.
Now you would have a point if it's something repetitive.
Which can be accurate for coding a vn in renpy. But that also ignores the fact that coding is unlikely to be the big hurdle here. It's a fairly straightforward vn, most of the effort likely goes into writing and rendering (constructing scenes, poses, camera placement).
