I'm trying to find a game I used to play on my school's pc

For context, up until late 2019 my school used Linux for the computing classrooms. I remember we had access to said PCs ever since kindergarten, and as far as I recall we played games like Tux Paint (my favorite one honestly).

There was this one though, it was kind of a dark fantasy, point and click type of game that took place inside of a castle. I'm not exactly sure about the character that we controlled, but I remember it being short, kind of like a goblin.

I know for SURE I played it. I'm 100% sure I did because it was kind of popular in my classroom. Now that I use linux I'd like to replay it!

If the description rings any bells, please let me know! I've been trying to find it but it's been at least 15 years since I last played it.
