There's a bit of confusion, the Ren'Py version is up to 0.70; the RPGM version is up to 0.75 and from the default preset slot 38 it goes to the end of version 0.70 both Ren'Py and RPGM. If you start before this point, that is as you mentioned from 0.65 or from the beginning, is not guaranteed the success of the game in RPGM, because the Dev said that the game is not complete, so you may encounter bugs, on scenes that are not activated even following the WT. I would suggest for those who don't like so much the RPGM to use the Ren'Py 0.70 version and get to the end of it then start from slot 38 with the RPGM version.
