Why start a new game with every version?I realize that by the time 29 is posted here 29.2 will be out and it'll be a constant cycle, which is the point, but eh, 29 seems like a good enough point to play on.
You can just copy the save game folder to the new version.
There's not that much that's been added that would make a person want to start a fresh save, and any "old" scenes getting CGs can still be viewed from the clear room, even if they'd been unlocked before the scene got the CG.
