I really like this game! Graphics and music are great, and the main idea is simple but good.
It is a bit funny that the caretakers see nothing problematic in a baby turning into an old man in front of their very eyes, but do find it weird to see a young person despite the many people probably visiting their grand parents (or maybe it is because of covid19 that made it so you can't visit your grandparents?).
I don't really have any suggestions, other than maybe working on that explanation system. I have multiple times accidentally pressed another button while in it and couldn't read it all. Maybe just make it so that it stops you but that you can still see it if you return to the same place again?
I also had a weird bug at the start, after the pit with the caretaker, I accidentally jumped over the pipe, assuming that you could continue ahead. I fell down and then nothing I did had any effect. I think you just forgot to put a wall in there but it might be more than that.
So yeah, great game! Really polished!
