I like that you take it in turns moving around the board, first you move then the adventurers move. It reminds me of Trap The Cat where you have to block the cats path. In my opinion, it seems a bit slow but maybe that's because I'm impatient XD
The game could do with some sort of background music or SFX, I feel that would make it more interesting. Tavern music or some sort of adventurer music would suit it. I think adding more adventurers would make the game more challenging, seeing as there's only 3, they can become quite distanced from the player, giving the player more space to move around. Maybe have the max adventurers be 4-6, they would fill up more of the board. I think eating them would be fun feature to clear up the board once max has been reached. Good game tho :)
