Hello! First of all, thank you for your kind words. I'm really happy to hear that you enjoyed the game :)
Regarding the unofficial upload, I had no idea about it until now. It's good that the game was taken down, although I'm not sure whether that was done by itch.io or the jam admins.
In any case, I would really appreciate it if you could share the username of the account that reposted my game, so I can report it and take further action.
Again, thank you so much for your curiosity, which led you to find the original author :)
