Don't mean to harp on this like everyone else, but what kind of coding did you do to get an impression like this?But from my own previous experience with coding: longer pauses between updates equals more wasted time. Procrastination sucks.
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).
