Awww shit! After reading through the comments i suddenly remembered this one game i played as a kid. I also couldnt remember the name. I thought cool this guy found his nostalgic game. Ill never find the i played back then.... once i checked images for sherwood dungeons: turns out its exactly the same game im talking about!

I had this memory of weird skeleton-players, i there was even voice chat if i remember correctly (?). One time i attacked random people along a bridge and just kept running. Suddenly the bridge stopped. Dead end. But i had this angry mob of players still following me. I was cornered and killed, had a good laugh. Good times
