To be specific I've downloaded an old version of the game before 4 months and from a random website and the story mode was working on it idk could I try to download it from another website ?

Ehhh, it'd be quite rude to discuss pirating the game right on the creator's page. On their latest update, no less.
That said, if you aren't able to support the dev (because of country restrictions, financial reasons, or otherwise), I'd recommend a forum like F95zone over random hosting sites, for safety -- it at least has an active community checking the links and commenting.
If you want to support the dev, though, it may still be worth checking with Majalis or the community hub to see if they have ways other than Patreon to donate.
