[TOMT] [VIDEOGAME?][EARLY 2000s] Computer game/videogame I used to play in school

So, I remember this game we used to play in computer classes during my schools years, so early 2000s (deffo pre-2007, and windows). It was 2D I believe and somewhat pixel-like (although 2000s graphics wouldn’t allow for much more, I think?), and I think you could choose between playing a girl or a boy as your main character. I vividly remember that there were different areas that were different ecosystems (like ice or forrest and such). I assume it was some sort of educational game because I ONLY played it during computer classes in school, but I honestly have no clue what were they trying to teach us lol

Going back to the pixel style, I remember you could move through squares (think about Undertale but you can only move one square at the time). And I think the squares were fairly big.

I’m losing my mind and I lowkey wanna play it again, please help!
