my 2 cents:
when you are not already established a long rework break will cost you supporters and it is possible that you lose interest in the game - the announcement of a rework is too often the last time one sees something about a game. would be a shame for this one, I quite like it :)
when you want to retouch the game: sure, fire away and have fun. but try to combine new content with updated older scenes in one release.
my main issues with the current game is:
* navigation in the convent. so painful, it is unclear if one of the blobs makes you rotate, moves back or leads to a different area. everything w/o a quick link can only be reached by randomly clicking around, I am simply too stupid to understand your approach :D
this could be mitigated by implementing a map-based navigation only for this area (probably quite a lot of work) or when you give the "navigation blobs" unique names as mouse-over text or similar. give me a chance to see where I end
* overarching story. both the MC and Momo are kind of colourless and don't show real interest, the strongest character is imo Melinda, showing initiative and driving the interactions between the persons. I don't mind a bumbling MC much (player agency is reduced with such a PC but I'm fine with simply along the ride) but what about Momo? that she's lazy and does not like to help fits her char well. but she should be *highly* interested to get mor followers and should be much more pushy, forcing the MC to find more potential nuns. and she ought to be socializing a lot with everyone, to spread the word. as goddess she's gone when she is forgotten.
* mini games. I hate them. sorry, completely my fault. it would be great when you'd provide an option to disable them - I am sure I am not alone disliking such game features and not everyone is able to patch the scripts to make them go away
