I searched all the terms I could think of with site:escapistmagazine.com and quotes on any terms I could find, and I read 100 pages of this topic with no luck. I've put in 20 hours the past three weeks looking for it... so please know that I did try my best before posting here and as such I am __super grateful__ for any help.
It was first person on a computer, a semi-educational game in the mid 90's. You were on an island (or was it a jungle?) and there was a bunch of science involved, for example there is a science experiment with droppers where you determine the bloodtypes of a few slides.
Movement outside these educational "minigames" (which I think you found by clicking on items displayed in the current screen,) was done frame by frame by clicking ahead on a path or at the bottom, which a new image overlay would show the zone you're "walking" in then. I m fairly certain you were the only human on the island.
There was a nest in a rock cliff-side by one of the main paths, and when you traveled on the path from the right direction a yellow-crowned penguin would hop down from the nest and look at you before waddling off.
Graphics were still images for most things (especially during movement outside of the "minigames", where you'd travel between "screen" by clicking on the path) but some things were animated simply such as the penguin and those droppers for the blood.
...I think I remember an easter island statue head, but I am not sure about that detail. And a rickety plank rope bridge. hrm... I think there was also a toucan at one point, just flying by.
The blood type thing had the slide in the center with two droppers and two spots of blood (maybe four? doubt it though.) The droppers would drip a chemical from their vial from the closest spot of blood on the slide and depending on how the blood reacted with each chemical you tried to guess the blood type. I think there was a note book explaining basics about blood and the like for educational purposes. It wasn't very useful from what I remember...
This blood type thing is what I remember most clearly because I felt so clever after figuring it out as a kid. I want to go back and beat the game
