Please please help, what game is this??????????

i used to play this game and it was really good, but now i can't remember it's name and can't seem to find it. i was wondering if anyone could help me. it's in 2d, you play as some kind of snail or slug. it was a puzzle game, kind of like an rpg. you could go to hell but i can't remember how. the was made of flat squares. im sorry i cant remember more, please help if you can. it is fairly old, maybe 8 years since i last played it. it is an online game. and in this one bit you had to get across a river and there was a guard there or something.thank you so much if you know it. i think it had a kind of 3rd perspective top down view.
