I would like to ask when it will be possible for the new version to inherit the CG animation from the old version.
Do you mean the unlocks? There were some larger changes to the save files from version 0.3 so loading in old saves got a bit messy. I've started making patches for saves going forward so progress shouldn't be reset from now on.
May I ask if you can provide some strategies? There are some CG animations that I don't know how to unlock.
