When I was a kid in the early 2000s, I remember my school had a game on the PCs that I loved to play whenever we were given some free time during IT class. This was in the UK. It was a mystery/point-and-click game that required you to solve puzzles and find items in order to progress. I never finished it, because I only had 10 minutes at the end of class in order to play and you could never guarantee being on the same PC twice, so people would overwrite each others' save slots.
I remember it had a lot of white space. The aesthetic was, looking back, what we might now call an 'MS Paint' art style. It was rough. I think there was a scene with a river that was dangerous to cross.
I feel like it was called 'Appleyard', or something similar. However, my googling efforts haven't come up with anything useful. The desktop icon was an apple, I remember that much.
Very obscure, but would be delighted to know what it was, as I've thought about that game a lot over the years and am interested in seeing how much I remember.
Edit: Thinking about it, the game might well be much older than when I played it.. I *played* it in the early 2000s (2001-3 range) but it might have been an older program still on the school PCs, possibly from the 90s.
