I don't even know how to describe the game(s) I am looking for since I can only vaguely remember. I don't know how old the games really are but I must have played them roughly 10 years ago.
In every of these (I think) 3 games you were located on an island. I don't know the exact objective anymore but you had to solve little riddles. The map was pretty small and there were certain objects/locations you could interact with. It was kinda like a point and click game but very simplistic. I cannot remember if I played these online or downloaded them (although I think i did not play many online games back then). I could be wrong about that but I think one of the riddles had something to do with an apple tree (I could entirely make this up in my mind tho).
I don't think I have a high chance of someone knowing what I am talking about but it is worth a shot 🙂
