I finally got around to unpacking the game. There was only 1 or 2 images that you wouldn't have been able to see with the previous version so you're probably better off not bothering yet.
On an interesting note I can tell everyone what caused the filesize to increase so much. The MC and it's... futanari partner each have upwards of 1000 "pose" pictures ( The ones that show up when they're talking). I'm no RPGMaker expert but it seems like there should be a way to do a composite image for those i.e. layer 1 for the body and head, layer 2 for the arm positions, layer 3 for genitals, layer 4 for eyes, layer 5 for mouth, layer 6 for blushing. Instead of having an image for each combination of those layers, have RPGMaker take the pieces for each layer and combine them itself and that would decrease alot of the work the dev seems to be stuck doing along with the file bloat.
