Good thing they are often available. On the website, the creator fails to provide old versions, which is ... not the best choice.I've got like 3TB of games, mostly because I keep a few versions back in case devs decide to nuke their games, like with this game for example, lol. I'm glad I have old versions cuz he's removed/changed so many scenes. Plus I download a lot of games to "archive" them that I probably won't play for years. My paranoia paid off when Patreon went full PC police, I have so many back versions of games that removed incest/sleep sex/hypnosis type content. I honestly don't know how I'd survive on a metered connection lol.

I had to go back to a v19 to try and fix my saves. For some reason, my old v19.5 savefile WILL NOT WORK whatever I do.
So I have to start from scratch.
I like this game, and it might be wise to re-play it as I am sure (as you mention) that I'd be missing out on stuff from earlier versions.
