I'm trying to find a 3d computer game in 3rd person view that I played as a kid on someone's computer a long time ago. I think it was on Windows 95 (could be older). I probably played it around 1999.
It was a point and click adventure where, at one point, the human protagonist is transformed into a frog/toad by a witch near a fountain/well. (This would end the game, as in perhaps you did the sequence of events in the wrong order or you were missing an item/quest and would need to reload.) I also think I remember there being a magnifying glass as one of the toolkit options.
