Hey, I thought I'd give some input on my experience now. I downloaded it and tried it when I kept a lot less tabs on my itch.io account - I doubt I knew I even had an open account at the time to leave my input. So a lot of this is from memory, but I'll share all the same.
I was excited to come across this, honestly. Reminded me a lot of the shimeji that I collected from deviantArt and loved to watch roam around my desktop while I was in high school - just keep it on for a long time and see how overrun it could get. And for the most part, I got that experience again with the goose and it was very in-character, I dare say.
But I came across the same crashing issues that Pawa reported, though I'm not sure if the triggers were the same. I'm not sure if the notepad elements were involved, but if I were to have the goose active for any substantial amount of time, it would eventually crash like that. Well, I say eventually, but I think it took like 10 mins tops.
Would recommend that ever got fixed.
