What is the name of this old mac puzzle game?

Hello! When I was a kid I played this game on my grandparents' old Macintosh. I feel like it came with the computer when they bought it. Unfortunately, I have no clue what version of mac it was but it was probably something that came out mid 90's maybe early 2000's It was really similar to Myst in the sense that you were stuck somewhere and you had to figure out codes and passwords to doors and clicking on things to escape. It was all pixel graphics and in a third person view. The world it took place in I remember having a sort of sun and moon theme to some of the parts and being really colorful. I remember the name of the game being "spelunking" but I know that's not the real title, that's just what I called it.

Sorry if this is really vague but I'm having a lot of trouble remembering the details. I just remember it being really unique and creepy and I would really love to maybe play it again some day. Any details I gave unfortunately could be totally off... so any help you can give me is really appreciated! Thank you so much!
