Yea, when i saw that the only way you can play old version is purchase $15 patreon tier, i understood that i need to save every available version for myself..

Well... technically, you have a point.
It's a tricky situation. On one hand, the game is free, but the old version isn't. There's no anti-piracy protection, yet you can't download old version from the official site.
However, the forum rules don't explicitly prohibit posting links to other sites or sharing old versions of the game. They only mention being good and avoiding spam.
So, technically, I'm not violating any rules :)
But thanks for warning :3
