Well, wasn't this an interesting little experience.
I am not gonna lie, I was expecting something else and am a little disappointed I did not get it. I was expecting more of a mess-with-your-head game where Buddy speaks to you (living up to his premise of being an AI Friend) and gradually getting more disturbing based on your responses. In fact, based on your description, I found Buddy oddly quiet, but maybe I simply plowed through the endings too fast.
That said, I do rather like the premise and the various solutions leading to all the endings, many of which are things similar games would find contrived ways to keep you from even trying, and the implications in some of the endings are delightfully disturbing (as is that secret little thing when you et all endings and the nice menu touch).
It's a pretty fun and interesting little point and click escape room with many possible solutions using only a few Items, which is definitely a cool take. So, good hob. I enjoyed it despite it not being what I thought it would be for certain.
